I suppose that ARIN would say that they do not guarantee routability
because they do not have operational control of Internet routers.
However, Wouldn't you say that there is a very real expectation that
when you request address space through ARIN or RIPE that it would be
routable?  I would think that what ARIN and RIPE are really saying is
that they issue unique addresses and you need to get your service
provider to route them. FWIW, the discussion of the military having
addresses pulled back is pretty much a non-starter unless they want to
give them back.  When the management of IP address space was moved from
the US DoD, there were memorandums of understanding that the military
controlled their assigned address space and nothing would change that.

Yes, but making a change (regardless of size) on a given platform is often
dwarfed by the effort of getting the update pushed out, to every possible
instance of said platform.  Multiply that by the number of platforms ...

With IPv6, it is a bigger single change (in code terms), but the hard part
(deployment) is roughly the same order of magnitude in deployment.

It is also easier to know if your platform is in an area that now has IPv6,
vs a router discovering whether or not the hosts understand the new /4.
That is, dual-stack (IPv4 + IPv6) create fewer problems than the
coexistence of nodes supporting 240/4 and not supporting 240/4.

And again, an additional IPv4 /4 is *just a bit smaller* than what IPv6
brings to the table ...

it for you - that does not guarantee that any other network anywhere else on

From a practical point of view as a service provider, I would assume my
customer would not be pleased to be assigned an address that prevented
them from communicating with anyone on the Internet that wants to
communicate with them.  We can debate the details of who does what but
every network operator will have to deal with their own customer.  If
they have an address block assigned to them, they will most likely want
me to route it as well as work with any other service provider to ensure
that they can get where they need to go.  For example, if one of my
customers cannot get to anyone on ATT or Comcast they will expect me to
solve the issue for them.  

As the customer's single point of contact with the Internet we
effectively have to deal with all of their issues even if they are
caused by another service provider.

All the ISPs raise your hand, if you were assigned a block of address
space by ARIN or RIPE and you could not globally route it, would you be
upset?

Of course there are times I want a globally unique address space and do
not want to route it but the whole point of being globally unique is
that I would like the option to route it if I wanted to.  The
requirement for globally unique but non-routable space is most
definitely an edge case, not the norm.

 My point is that blaming union contracts or union anything for being
 unable to find a place to hold a convention where you can implement
 the network you want to implement is nonsense. NANOG, ARIN and IETF
 conferences have all somehow managed to implement their own effective
 networks. Even in union towns. If Worldcon's site selection committee
 can't find a suitable host, that's their deficiency.

That's as may be, Bill, but it is definitively outside *my* personal scope,

the burgers had 128 (bacon) bits and we served IP(A) to drink :-) You
can see some photos at:
http://www.networkworld.com/community/blog/scenes-ipv6-day-barbecue

But we came up with another interesting measure for the vastness of
the IPv6 address space:

If an IPv4 hamburger patty has 2^32 (4.2 billion) unique addresses in
its 1/4 inch thickness, how thick would an IPv6 hamburger be (with
2^128 unique addresses)?

The answer is... 53 billion light-years.


Just got to playing with this today, trying to put it in some sort of 
perspective.  First off, lets bring that down to human-sized numbers, 
using standard units used in astronomy:


2^94 inches = 16 gigaparsecs + 304 megaparsecs + 322 kiloparsecs + 752 
parsecs + 2 lightyears + 57101 au + 23233 earthradius


(Gigaparsecs isn't very common, but that's because it's a bit big.)

So...  How big is that?  What can we compare it to?  Well, let's start 
at the top: does this thing actually fit in our universe?


The size of the observable universe is set by the Hubble Constant and 
lightspeed: The Hubble Constant is the rate of growth of expansion in 
the universe - the redshift phenomena.  The further away you look, the 
faster things are moving away from us.  At a certain point, they are 
moving away from us faster than light, meaning that light coming from 
them would never reach us.


That's about 14 gigaparsecs away.  (Adjusting for such things as how 
much they will have moved since you measured them.  There's a whole 
rabbit hole to go down for this, on Wikipedia alone.)  Which means the 
observable universe is about 28 gigaprsecs across.  (Now you can see why 
gigaparsecs isn't a common unit.)


So our hamburger patty would fit inside it - but you wouldn't be able 
to see one end from the other.  Ever.  In fact, while someone at the 
center could reach either end, once they got there they'd never be able 
to reach the other.  They wouldn't even be able to get back to where 
they started.


Which of course means that even if you ate at lightspeed, you'd never 
be able to eat it.


(Oh, and if it still has a radius of 3 inches - standard 1/4 pound 
burger at 1/4 inch thick - it's got a volume around that of 11,000 
Earths, and a mass of about 1,400 Earths, about 4.6 times the mass of 
Jupiter.)



It's straightforward unit conversions. There are 2^96 IPv4 Hamburgers
at a quarter-inch apiece. That's 2^96 inches/4 (2^94 inches).
Switching to decimal units, 1.98x10^32 inches; 1.65x10^27 feet;
3.13x10^23 miles; and then continuing to convert to light-years.

A good tool for this kind of wacky unit conversion is Frink

(http://futureboy.us/fsp/frink.fsp?fromVal=2%5E94+inchestoVal=lightyears),
which can do this in one shot. Simply enter:


I prefer the 'units' program, which is usually a standard utility on

IPv4 has a train load of devices unicasting and retransmitting all the

configure based on reception of a single packet. Therefore IPv4 is
suboptimal in its abuse of the air link which could have been used for
real application traffic instead of being wasted on device configuration.
Thus by extension using your logic it is not operational. 


Just because you personally want IPv6 to be nothing more than IPv4 in every
aspect is no reason to troll the nanog list and create confusion that causes
others to delay their IPv6 deployment. Your complaints about IPv6 behavior
on wifi ignore the point that IPv6 ND behavior was defined before or in
parallel as wifi was defined by a different committee. There will always be
newer L2 technologies that arrive after an L3 protocol is defined, and the
behavior of the L3 will be 'suboptimal' for the new L2. When the issue is
serious enough to warrant documentation, addendum documents are issued. When
it is simply a matter of personal preference, it is hard to get enough
support to get those documents published.

the economies of scale of a Worldcon, and how to make this topic relevant to Nanog

2012-09-20 Thread Jo Rhett
In a message Jay had apparently forwarded from offlist (or I missed the 
original) Rick said:

 success of the event.


This points out another significant facter to why network isn't part of what's 
negotiated here. Internet is *not* considered mission critical by most 
attendees. Cheaper hotel rooms, adequate facilities, and inexpensive food 
nearby are the top three items Worldcon attendees complain about. So it's not 
going to be on the top of things to focus on.  (and why this topic as it is 
being discussed is not relevant to this list)

Those of us who feel Internet access is mission critical carry LTE network 
devices or make other arrangements. Obviously the growth of smartphones and 
tablets is starting to change that equation, but at the moment none of the 
Worldcons have done a very good job of providing useful online interaction so 
there's no actual use for onsite data related to the conference itself. 
Obviously I would love to see this change.

For those who care about the economics of Worldcons, the following post is from 
a person deeply involved in the organization which holds the rights and 
trademarks for Worldcon. (Think Olympic Site Selection Committee, except they 
don't select the locations -- the members do)  He covers a lot of the topics 
about why Worldcons are so very, very different from any of the conferences 
listed above, and why the economics of scale these conventions have don't work:
http://kevin-standlee.livejournal.com/1166167.html

Now, if we want to make this topic relevant to Nanog, the operative question is 
the feasability of a data provider putting good wireless gear near these 
facilities and selling data access to attendees. For a useful comparison, the 
2010 Worldcon in Melbourne had an expensive wifi service in the building that 
kept falling over. A cell provider across the street put up banners advertising 
cheap data service, and put people on the sidewalk in from of the convention 
selling pay as you go SIM cards with data service. They made brisk business.  
*THIS* is where us network operators can provide good networking service to a 
large facility, and pretty much kill the expensive data plans operated by the 
facility.

Instead of building up and tearing down a network for each convention, put an 
LTE tower near the facility and sell to every group that uses the convention 
center.

your argument be that 'the stack vendors broke what I want by not believing

To some degree yes. In this particular case, why don't you personally go out

be shipped version of software so you can make use of a handful of addresses
and buy yourself a couple of years delay of the inevitable. If you can
accomplish that I am sure the list would bow down to your claims that there
was not enough effort put into reclamation. 

 
 Let us spin this another way. If you cannot even expect mild change such
as
 240/4 to become prevalent enough to be useful, on what do you base your
 optimism that the much larger changes IPv6 requires will?

240/4 is only 'mild' to someone that doesn't have to pay for the changes.
IPv6 does require more change, but in exchange it provides longevity that
240/4 can't. 

Denial is  a hard thing to get over, but it is only the first stage in
process of grieving. IPv4 is dead, and while the corpse is still wandering
about, it will collapse soon enough. No amount of bargaining or negotiation
will prevent that. Just look back to the claims in the '90s about
SNA-Forever and 'Serious Business doesn't operate on research protocols' to
see what is ahead. Once the shift starts it will only take 5 years or so
before people start asking what all the IPv4 fuss was about. 

IPv6 will happen with or without the ISPs, just like IPv4 happened despite
telco efforts to constrain it. The edges need functionality, and they will
get it by tunneling over the ISPs if necessary, just like the original
Internet deployed as a tunnel over the voice network. You can choose to be a
roadblock, or choose to be part of the solution. History shows that those
choosing to be part of the solution win out in the end.

 What is not amusing is continued evidence that the lessons from this debacle
 have not been learned.

Or that other past lessons are being forgotten.

 Baking in bogonity is bad.

Ok, but the bogonity is baked in in two areas already; both 240/4 and IPv6.

240/4 is baked in (or out) of IPv4 on a large quantity of deployed
firmware and devices, and larger quantity of local OS IPv4 stacks.
The local OSes are, as a rule, upgraded on 2-3 year timelines and
patched in many cases something like annually or every few months.
Firmware, less so.  As someone else pointed out, a lot of those
devices are not under support anymore or from now defunct vendors, so
a hardware replace is the fix.

IPv6 was also baked out of a large quantity of deployed firmware and
devices, and OS stacks.  This has largely already been remedied, and
people are largely aware that device firmware that's not upgradable
needs replacement, so the fix is mostly in and already most of the way
through happening.

In both cases, a roughly 7-10 year total process in practice; in one
case, we're already 5-6 years of serious effort in to it.

Do you understand the difference between starting a 7, 8, 10 year
process fresh from zero right now versus continuing one we're nearly
done with?

 Predicting the (f)utility of starting multi-year efforts in the present for
 future benefit is self-fulfilling.

No.  This is a classic techie-makes-business-failure problem.

You are not creating products for today's customers.  You're creating
products for customers who will be there when the product is ready.
You're not creating a product to compete with today's products; you're
competing with the products that will be out when it's done and
shipping, and that come out subsequently.

This is what market window is all about.

 Let us spin this another way. If you cannot even expect mild change such as
 240/4 to become prevalent enough to be useful, on what do you base your
 optimism that the much larger changes IPv6 requires will?

We're somewhere around 2/3 of the way through on the IPv6 changes.  We
haven't started a 240/4 activation project yet.

We have found while doing the IPv6 that there are some glitches; a
very few of them at protocol level, with so-far tolerable workarounds
or adjustments in expectations.  A lot of them at operational process
and usage levels.  A lot more of them at business / user levels.

There's a difference between IPv6 doesn't work and IPv6 is not
perfect.  IPv6 is deployed, running nationally, represents 0.6-1.0%
of active IP traffic right now to big websites depending on who you
talk to (Google was 0.6% I think, Wikipedia reporting 0.8% on an
internal list a couple of weeks ago, etc).  It's obviously not
doesn't work as it's showing functional IPv6 traffic levels that
approximate those of the whole Internet 15 years ago.  It's obviously
not perfect.

It's asserted that the operational problems are big for a number of
sites, but others are making it work.  We'll have to see on that.

In any case, it's not 7-10 years away from working.  Even if we have
to respin a support protocol (DHCPv6.1, anyone?) the core protocol and
most of the stacks and the routers and devices probably wouldn't need
replacement.  Someone who objects to current operational issues is
likely to eventually (soon) just write code rather than wait for
arguments to settle and the protocol wizards to pronounce.  Running
code trumps theory and argument.


If you think you can accomplish a full 240/4 support rollout across
the world's devices and infrastructure faster than we can get IPv6
running, I would suggest that you reconsider.  It's an easier fix at
one level only - the code in the stacks that needs changing is
relatively minor.  Even if the protocol and code changes were
completely done tomorrow by magic, the deployment phase, all 5+ years
of it, is starting at zero.  IPv6 is deployed; not universally, but
most of the way through.  We're shaving operational issues with the

That's a big burger. But not so big as you thought. By 17 orders of magnitude.

In point of fact, a mere 150,000 people put together will eat all that

population could chew through it in half a day.

Worse, that's if we were managing IPv6 delegations the way we manage
IPv4 delegations. We're not. We're using sparse allocation. And 6RD.
And default customer allocations of 65,000 LANs. And other interesting

 IPv4 is dead, and while the corpse is still wandering about, it will
 collapse soon enough. No amount of bargaining or negotiation will
 prevent that. Just look back to the claims in the '90s about
 SNA-Forever and 'Serious Business doesn't operate on research
 protocols' to see what is ahead. Once the shift starts it will only

 ipv6 has none of these benefits over ipv4. 

You are comparing IPv6 to the historical deployment of IPv4. Get with the
times and realize that CGN/LSN breaks all those wonderful location-aware
apps people are so into now, not to mention raising the cost for operating
the network which eventually get charged back to the user. 

 The only thing in its favour is a
 scalable addressing model.  Other than that, it's a world of pain with

(even on
 service provider equipment - and both vendors C and J are guilty as

 here),

Nanog in general has a problem taking the myopic viewpoint 'the only thing
that matters is the network'. The real costs are in app development and
support, so crap in the middle of the network (which is only there to keep
the network managers from learning something new) will be worked around.
While shifting apps to IPv6 has a cost, doing that is a onetime operation
vs. having to do it over and over for each app class and new wart that the
network managers throw into the middle. IPv4 even with all its warts makes a
reasonable global layer-2 network which IPv6 will run over just fine. (Well
mostly ... I am still chasing a 20ms tunnel asymmetry which is causing all
my IPv6 NTP peers to appear to be off by 10ms)


 poor application failover mechanisms (ever tried using outlook when
 ipv6 connectivity is down?), etc.

Outlook fails when IPv4 service is lame (but I could have stopped at the
second word). I use Outlook over IPv6 regularly, and have had more problems
with exhausted IPv4 DHCP pools than I have with Outlook over IPv6 in the
last 10 years. 

 
 The reality is that no-one will seriously move to ipv6 unless the pain of

That depends on your time horizon and budget cycles. If your org suffers
from the short-term focus imposed by Wall Street, then you will have a hard
time making a case before the customers have started jumping ship in
significant enough numbers that you will never get them back. If your time
horizon is measured in decade units, you will have an easier time explaining
how a 5 year roll out will alleviate costs and minimize pain down the road.
Most of the press and casual observers didn't get the point of the 2003
DoD/US Fed mandates for 2008. That date was not picked because they believed
they needed IPv6 in production by 2008, it was picked because they had
significant new equipment purchases starting at that point that would be in
production well past the point when it becomes likely those devices will
find themselves in some part of the world where 'IPv6-only' is the network
that got deployed. The only way you turn a ship that big is to set a hard
date and require things that won't make sense to most people until much
later. 

 
 I wish I shared your optimisation that we would soon be living in an ipv6
 world, but the sad reality is that its sorry state bears more than a

If operators would put less effort into blocking transition technologies and
channel that energy into deploying real IPv6, the sorry state wouldn't be
there. For all the complaints about 6to4, it was never intended to be the
mainstay, it was supposed to be the fall back for people that had a lame ISP
that was not doing anything about IPv6. All the complaining about 6rd-waste
is just another case of finding excuses because an ISP-deployed-6to4-router
with a longer than /16 announcement into the IPv6 table does a more

In theory, that sounds great.  However, the legal basis for actually

 Heavy reliance on broadcast for a wide range of instances where the

 sub-optimal.

It's not sub-optimal w.r.t. link bandwidth, if the link is
a broadcast domain. Moreover, broadcast is no worse than
all-node multicast.

And, given the CATENET model of the Internet to connect
broadcast domains including small number of devices by

 On the other hand, the scarcity is of *globally unique routable*

 an internal network that isn't announced to the public Internet
 doesn't have to worry about happy eyeballs, broken carrier NAT, and
 the like because it doesn't have to be connected to them if it doesn't
 want to be. A lot of the transition issues are much less problematic
 if you're not on the public Internet.

 Actually, they're not any different, aside from scale.  Some private
 internets have hundreds to thousands of participants, and they often use
 obscure protocols on obscure systems that were killed off by their
 vendors (if the vendors even exist anymore) a decade or more ago, and no
 source code or upgrade path is available.

 The enterprise networking world is just as ugly as, if not uglier
 than, the consumer one.

I haven't worked much on the commercial private internets, but I did
work for someone who connected on the back end into numerous telco
cellphone IP data networks.

For all of those who argue that these applications should use 1918
space, I give you those networks, where at one point I counted
literally 8 different 10.200.x/16 nets I could talk to at different
partners (scarily enough, 2 of those were the same company...).  And
hundreds and hundreds of other space conflicts.

Yes, you can NAT all of that, but if you get network issues where you
need to know the phone end address and do end to end debugging on
stuff, there are no curse words strong enough in the English language.

Re: Verizon IPv6 LTE

Safari is definitely preferring IPv4.

In a happier note, if you tether a device via hotspot on an IOS6 iPad, the 
clients get native IPv6. Strangely, they get addresses out of the same /64 as 
the iPad's LTE interface. Anyone know how that is working? I would have thought 
they would use prefix-delegation, and there would be a separate routed /64.

thanks,

 So, a single example of IPv4 behaving in a suboptimal manner would be

 For example?
 
 Your own example ---

 ...  that a very crowded train arrives at a station and all the smart
 phones of passengers try to connect to APs ...
 
 IPv4 has a train load of devices unicasting and retransmitting all the
 dropped packets,

IPv4 merely need a broadcast ARP request and broadcast DHCP discover
to be piggy backed in a single IEEE802.11ai frame reliably unicast
to an AP.

 where an IPv6 multicast RA allows all the devices to
 configure based on reception of a single packet.

You miss multicast storm caused by DAD.

 Just because you personally want IPv6 to be nothing more than IPv4
 in every aspect is no reason to troll the nanog list and create
 confusion that causes others to delay their IPv6 deployment.

Just because IPv6 is working without much problem somehow somewhere
is not a valid reason to say others should use IPv6.

As IP is so essential to the Internet, IP protocol must be
perfect w.r.t. the scale and diversity of the Internet.

IPv4 has evolved so, as the Internet evolve.

IPv6 could have been so, if it were a exact copy of IPv4 save
address length.

But, it is not, which is why IPv6 failed on various points
which are different from IPv4.

 Your complaints about IPv6 behavior
 on wifi ignore the point that IPv6 ND behavior was defined before or in
 parallel as wifi was defined by a different committee.

The problem is ND uber Alles approach, which makes it impossible
to make IP uber Alles.

 There will always be
 newer L2 technologies that arrive after an L3 protocol is defined, and the
 behavior of the L3 will be 'suboptimal' for the new L2. When the issue is
 serious enough to warrant documentation, addendum documents are issued.

Because of ND uber Alles approach, the document just says IPv6
works suboptimal without solving the issue.

OTOH with IPv4, the document can solve the problem by having
a new adaptation mechanism much different from ARP or PPP.

Prefix delegation isn't generally available in mobile networks yet, 
that'll come in the next few years. It's probably using ND proxy or 
similar technique.

Please don't hack or ddos it :-) 

Unfortunately, while you do get an ipv6 address, mobile terminated data
doesn't work, so you don't have to worry about this.  It is firewalled by
Verizon.

I actually tried to set up a VPN on a LTE data card using the ipv6 address
since the IPV4 one is behind carrier grade NAT.  I found out the hard way
that was a no-go, either.

One more tip:  IPv6 will work over the legacy 3g network.  Don't ask me
much about it, but it tunnels it using eHRPD to the same IP/IPv6 headend
to enable seamless EVDO/LTE handover.

 I'm guessing there will be a lot of new ipv6 traffic from LTE handsets on
 vzw tomorrow.

 Should be interesting if apple turned on their Phobos domains for App
 Store as v6 via akamai. I would expect a lot of traffic to shift then.

Interesting. Does this happens only if you start out in LTE coverage and
then roam onto EV-DO, or does IPv6 work if you connect to the network
outside of LTE coverage too?

I wonder if there will be similar magic provided for UMTS/LTE networks..

I doubt it. The path there should be to upgrade GSM/UMTS network to 
release 9 and support v4v6 pdp context and then you don't need any magic 
at all (as far as I can tell).
