This change appears to have been completed, as of root zone serial 2013010300:

[krill:~]% host d.root-servers.net
d.root-servers.net has address 199.7.91.13

D.ROOT-SERVERS.NET.  360    2001:500:2D::D
[krill:~]% 

The authoritative location of the root hints file is 
ftp://rs.internic.net/domain/named.root and those who feel like being tidy 
DNS admins could pull a fresh copy from there so that the next time their 
nameserver is restarted it will prime optimally.

As discussed at some length before, those who prefer to be more hands-off about 
this will very likely see no negative impact from their laziness.

I am not one of the people who works with root zone management, but I 
understand that:

 - the normative location of the root hints file is 
ftp://rs.internic.net/domain/named.root
 - some of the other mirrors take a few hours to update

Err, no.

The root zone changes twice a day and its contents change quite frequently as 
TLD managers update their name servers, do key rollovers, etc.

If you're going to copy the root zone, I'd recommend using a zone transfer from 
the name servers described in http://dns.icann.org/services/axfr/ or, at the 
very least, set up a cron job to pull the root zone twice a day.

While it is sometimes required to perform changes, it is no wonder that

from UMD to behave accordingly (not that they are not, but just in the grand

I am pretty sure that UMD doesn't think that the D root is akin their

as you would suggest in your mail (their infrastructure, their server,

not owe anything to anyone, etc etc...)

It is critical to all of us, and we can and should lend our advice or

(and sometimes require) a level of assurance that we (that is the

It is their decision to make ultimately, but they can and should hear 
us, and if there
is actually a grain of wisdom in what is being said, to consider it and

While there is no specific and contractual SLA in place, that does not

I believe you are assuming that the department which runs tne root
server at UMD has a choice in the matter.

Consider a campus-wide IPv4 address space reorganisation to make better
use of their available space. It would make sense to do this during
summer when students are away. Having to stop using that IP by June
would fit that scenario.

The scarcity of IPv4 will result in more and more streamlining of
network address spaces within organisations.

While I have seen this announcement because I subscribed to nanog, I
wouldnt be surprised to see that news spread via many other means.

And how much more warning would one really need ?

It isn't as if they were to announce that the end of the world will be
this coming friday. (that one was announced centuries ago and isn't
getting much press :-)

This is a simple change, the internet will not stop running. It may take
an extra second to reboot the bind servers that haven't gotten updates.

I gently point out the following resource (which I'm sure nearly 
everyone here already knew about):


http://www.zakon.org/robert/internet/timeline/

DNS first reared its head in 1984. For the very longest time I even kept 
my copy of hints updated by hand, leaving notes as to the old IP, so 
that I'd notice if anything from my end was trying to reach an old IP 
(the amount of stupidity hard coded in was just as bad then as now).


I downloaded one of the last hosts.txt files, in 1992, out of sentiment. 
It still makes me nostalgic to look at it.


Is it just me? I do not remember L or previous entries garnering this 
much attention, and it seems there was actually a bit less time between 
announcement of the change, and my ::face::palm:: when I saw log 
entries, and realized I was lazy. I have no idea when the IP was turned 
off, since it wouldn't have *mattered* to me. I do remember quite a bit 
of discussion here and there when the first ones were changing, but it 
was local discussion, when my world was a bit more narrow and focused.


I did actually look (although not very hard) for an actual history of 
the original hosts, and the migrations from legacy IPs and legacy names 
into the less colorful format of *.root-servers.net that we know and 
love today.


For those of you still worried, I promise it will all be okay. I promise.

Hi,

 Additionally, we will be actively monitoring usage after the 6 month
 period to determine when best to terminate the service on the old IP.

Good to hear that.

 The old address, which is in the middle of UMD's network, is going to be
 black-holed once the change is over. Nothing will be on that IP once we
 move the root off.

Thank you, very important to get that confirmed :-)

 Additional notice to other listservs and on web pages is coming soon.

Hosts like that should be using forwarders, not running their own

Outside of VAX-VMS or old Windows systems I doubt there's much out there
that runs a recursive resolver that can't just have the current version

systems, but the vast majority of those are so broken that an out of

 Remember nameservers will start logging warning messages as of January 3rd.

And if they do, recursive service operators who haven't seen the message will

It's a question of what's procedurally sensible.  Sensible things would

widespread notice of what's happening and generally not poking around with
really important bits of the Internet at times which are well known for
having configuration freezes and/or when many people are going to be on

affect small areas, but this change will affect everyone even if they
people don't realise it (and yes, it probably won't affect them visibly
because of root cache repriming).

Other sensible things might include:

- liaising with operating system vendors and recurser servers code authors
and providing them with extra advance notice so that they can roll these
changes into their code in a structured way.  Software update release
cycles often take many months to roll out, particularly for non OSS code.

- perhaps some targeted localisation of the d.root-servers.org notice so
that more than 15% of the world population can read it (english == 5%
native speakers, 10% second language)?

Lots of people are aware that resolver dns servers will automatically
reprime their root cache without manual intervention.  However, not
everyone will realise it and a random punter who looks at this notice and
doesn't understand root cache mechanics may well think that they need to
start updating their DNS configuration files on Jan 3.  It's not clear from
the change notification that you don't necessarily need to do this.

This change wasn't planned over a coffee last thursday morning.  It's
obviously been on the cards for several years, so asking for more carefully
structured notice in a procedurally sensible sort of way isn't an
unreasonable thing to expect as part of the migration plan.

You have 6.75 months to implement this before the current IP address no
longer works. Use idle time during holidays to plan when you will do
this change if your configs are frozen during holidays.

I did react with a sense of urgency when I first read the message, but
once you re-read it, you realise the timing and advance notice are
plenty sufficient.


 Software update release

Those one support can get a patch from their vendor or simple

address it in (or use dig to get the new one).

Given reality and the way root priming works, 3 weeks notice and 6 months of

 more widespread notice of what's happening

I gather recursive server implementations provide a warning message telling

notification methodology than sending email to a few (or even many) mailing

 having configuration freezes and/or when many people are going to be on
 holidays.  

It simply doesn't matter if folks refuse to make a change during the holidays. 
The worst case scenario is they'll get a warning message in their recursive 
server log files. Presumably, the folks who look at those log files will be 
able to understand what it means. They have 6 months after the change occurs to 
update their root hints.  Even if they don't, this particular change will only 
affect people 1/13th of the time their name servers reprime and will do so in a 
way that is wildly unlikely to even be noticed.

 This change wasn't planned over a coffee last thursday morning.  It's
 obviously been on the cards for several years, so asking for more carefully
 structured notice in a procedurally sensible sort of way isn't an
 unreasonable thing to expect as part of the migration plan.

You seem to be a bit confused about roles and prerogatives here.

The UMD folks are making a change to _their_ infrastructure. They have sent out 
a notice in advance of that change to folks who might be interested. They were 
under absolutely no obligation to do so. There is no contractual or service 
level agreement between UMD and _anyone_ that requires them to do _anything_ 
with regards to root service. The fact that they gave 3 weeks notice that they 
were changing the IP addresses of their server shows they are nice folks. 
Neither you nor anyone else that uses D has any right to dictate how UMD 
operates their infrastructure, how much notice to give when making changes to 
that infrastructure, who gets notified, etc. 

Welcome to the wonderful wacky world of volunteer root service!

With that said, I would argue it should be the responsibility of the 
maintainers of the root hints to notify software vendors, recursive operators, 
etc. of a change since the maintainer of the root hints file has 
vetted/implemented the change.  It is also more likely that the world has at 
least heard of the maintainers of the root hints than some random person 
posting unsigned messages from a University (no offense Jason :-)).

the end of 2013 week one or week two), and where two of those weeks are

In addition, there is no further announcement notices on

You are absolutely kidding, right?

Can I politely ask you / UMD to please reconsider the timing and

consequences for the entire globe.

If you decide reconsider this change, could you please:

- change the date to give the world several months warning.

- change the date something which doesn't conflict with any of the major
ethnic world holidays

- create notification pages on www.root-servers.org, d.root-servers.net,

If I had to guess, I would guess that renumbering is likely required to get it 
into a more portable address assignment from a multi-homing perspective.  Look 
at the whois information below


If I were hosting a root server or something similar, I would certainly want it 
segregated enough that I could manage multi-homing for that address prefix 
outside of my other networks.  

In this case, I'd assume UMDNET-1 may have monetary or administrative policies 
regarding the ability to be multi-homed and the degree to which it can be, 
however providing multiple links to UMD-ROOTD-NET is likely much easier because 
those decisions (or cost of connections) don't necessarily need to affect

you might want to pick up the new belt/suspenders file aka root.hints, 
named.ca, et.al.
and install it on your servers in the course of the next two years.

if you can't reach D, then you should be able to reach the other 12.

i beleive that D has not changed its IP address since before the RIR system 
came into
existance and therefore had no idea what PI space means.   Some of this stuff 
is
really old/stable and making changes to foundational/stable systems is fraught 
with
peril.  Being careful is just being prudent.

Perhaps of real interest to the NANOG community is the ability to see this 
prefix

When nameservers first boot, all they have is a hints file. This is either 
baked in to the software, or provided as a hints file, or some combination. 
The hints file you have today will have the current/outgoing D-Root address.

The first thing a resolver does before it is ready for service, again, armed 
only with the hints file, is to send a priming query to a root server. This 
query is of the form . IN NS?. Resolvers will try servers from the hints file 
until they get a response. Once the priming response is received, the data 
originally harvested from the hints file can be thrown away.

Once D-Root renumbers, a freshly booted resolver with an old hints file will 
either:

 - send a priming query to one of A, B, C, E, F, G, H, I, J, K, L, M, and 
obtain a response that contains the new D-Root address
 - send a priming query to the old D-Root v4 address, and also obtain a 
response that contains the new D-Root address

Once service is discontinued on the current/outgoing D-Root address, such a 
resolver might fail to obtain a response to its priming query if it happens to 
try the D/v4 address first. It will re-try with a different address until it 
succeeds. In principle, you only need one reachable address in the hints file 
to work to get up and running.

In summary, theory (and practice) tells us that:

1. You should update your hints file from time to time, and

2. If you don't, chances are overwhelmingly good that it will make no 
difference, and everything will work as normal.

I'm suggesting a lot more notification than 6 months before 128.8.10.90 is
switched off.  And corroborative announcements backed up from authoritative
sources, not just a single email to nanog.  It turns out that the Internet
extends far beyond the borders of continental north america, and this
change affects everyone who runs a resolver server.

It would be really good to have a formal public statement of intent from
UMD about their long term plans for 128.8.10.90 after retirement so that we
don't have a repeat of the L root hijacking debacle in 2008.

Everyone is extremely appreciative of the work that UMD has done in hosting
this service since 1987.  However, hosting a root server is a pretty big
responsibility which includes maintenance of not just the existing
addresses, but also all historical addresses to ensure that people who hit
them after retirement (whether now or 20 years down the line) are not
served bogus data.

i had one, back last century, when B renumbered. the old address of B 
was the last
working address in the bootstrap file from 1986.  :)

i'm fairly confident that 99.% of all the existant bootstrap files 
on the Internet
today contain at least 9 working IP addresses for root nameservers.


That said,  its -very- important to ensure (at each ISP, worldwide) 
that you have

 In point of fact, ISTM that there *is no way* to make this completely safe;
 granted that it's a low percentage attack, and thus probably not useful
 to actual attackers, but the possibility exists that someone could hijack
 that block at a provider level, and provide their own replacement for that
 old server IP.
 
 
 This is an extremely good point...   Where will the former addresses be
 going after this?

As I understand it (but ask UMD!)

 - D-Root is currently numbered out of a general-purpose UMD /16 into a 
dedicated, specifically-assigned /24
 - the UMD /16 is not going anywhere

The announcement is that D-Root is being renumbered, not that UMD is 
renumbering its whole network.

Other root servers have renumbered out of institutional, general-purpose 
networks into dedicated networks in the past. I think the last one was B-Root 
in 2004, from an address within 128.9.0.0/16 to an address within 
192.228.79.0/24 (see http://www.root-servers.org/news/new-ip-b.html).

 I'm sure someone's thought about that though...I hope.

 In summary, theory (and practice) tells us that:
 
 1. You should update your hints file from time to time, and
 2. If you don't, chances are overwhelmingly good that it will make no 
 difference, and everything will work as normal.

But this is important to those who write DNS server software to ensure
they embed the most up to date  version of the root servers in their
binaries.

There are also a number of much older systems which no longer get
software updates (such as VAX-VMS) so it is good practice to manually
maintain the root.hints files so that over time, you don't accumulate
more than a couple of disused root server IP addresses.

So, in short, UMD will still own the losing allocation, and be able to make 
relatively sure nothing else is placed at that IP (though of course they 
won't necessarily be able to make sure no one hijacks that entire prefix --
does Renesys have a pay-special-attention list?)

 Jason,
 
 
 You've just given 3 weeks notice for a component change in one of
 the few critical part of the Internet's infrastructure, at a time
 when most networks have entered a configuration freeze (which will
 usually finish at the end of 2013 week one or week two), and where
 two of those weeks are holiday / slack periods in large parts of
 the world where many people won't be working.
 
 In addition, there is no further announcement notices on 
 www.root-servers.org, d.root-servers.net, www.iana.org or
 www.icann.org.
 
 You are absolutely kidding, right?
 


Hi Nick, and Nanog,

I've given 3 weeks + 6 months (at least) notice on a service change that
will not be noticed by most anyone.  Its a change to the HINTS file, which
is only used on bootstrapping. So anyone who does not update it will
connect to any of the other 12 root-servers, and receive the updated IP
from then on.  If you have not updated your HINTS file since 1987 you may
have issues bootstrapping, but you are good from 89/09/18 on.
Additionally, we will be actively monitoring usage after the 6 month
period to determine when best to terminate the service on the old IP.

The old address, which is in the middle of UMD's network, is going to be
black-holed once the change is over. Nothing will be on that IP once we
move the root off.  The rest of UMD's network is staying put.  This move
is part of UMD's commitment to improve the service, so we can support
DNS anycast.

Additional notice to other listservs and on web pages is coming soon.

Thanks,

the smart-ass answer to the nagging question on prefix reuse
is:

Top Men are working on it

A more reasoned (maybe) response might be:

To my knowledge, there is tension between creating golden addresses
and address flexablity/reuse.   I'd really like to swing back toward
address flexability/reuse, but there is a whole lot of inertia behind
the golden address crowd.

Of the six renumbering events that come to mind, four of the prefixes
are sequestered.  The two that are not were in net 10.  I am unaware of
-anyone- who still points at the old addresses in net 10 space.

I think there were other renumbering events, but have not kept track 
of the old prefix use.

Would there be any impact to having the root servers immediatly provide

I realise that keeping the old IP functional for some time is important

As far as I understand, after 3 January 2013 such a dig command would
create a new updated file with the new IP address.

Hi Jean-Francois,

On the 3rd you should be able to dig and see the new entry, like the

Just a quick questionif the old block is going to be black-holed but
kept allocated...why does it need to be changed in the first place, or why
does the existing have to be disabled?  (just have both addresses
active/responding?)

Forgive me if I'm missing something.

because you would not accept a /30 cutout of the UMD /16 coming
from some random IX in Singapore.  (see Joe Ableys post earlier today

Agreed on the routing (although I wouldn't ever expect to see the subnet
encompassing a root server IP advertised in the wild with..anything even
close to 30 bits), and understood on the minimal/non-existant operational
impacts.  Guess I'm just being curious.
