That's OK.  I purchased a WAP from someone in Virginia and now I can't
get the Google App on my phone to admit that I'm still at home and not
in Broad Run.

If anyone has any idea how to "unglue" a MAC address from an incorrect
location in the guts of Google (I've done the skyhook thing
http://www.skyhookwireless.com/submit-access-point), please let me know
(this is an invitation for a followup).

Microsoft Geo-IP Admin needed

[Fredy Kuenzler]

Can anyone point me to a Microsoft Geo-IP admin? Their Geo-IP for
live.com/outlook.com seems to be rather outdated.

We get complaints for 85.195.208.0/20 and 85.195.224.0/19, pointing to
Antarctic instead of Switzerland. Any commercial Geo-IP shows correct
information, but Office product activation fails.

CIDR Utilization

[John Steve Nash]

Hi,

I'm looking for any tool or a way I could specify a CIDR and the prefixes
that are being used within this CIDR and the tool show me all free
supernets.

Example:

192.168.0.0/24 - CIDR

Used subnet's:

192.168.0.1/32
192.168.0.8/27
192.168.0.64/26
192.168.0.68/32
192.168.0.96/29

Tool Result => Free Subnet's:

192.168.0.2/31
192.168.0.4/30
192.168.0.32/27
192.168.0.128/25

Regards,

John

I've used subnetsmngr for this in the past. Proper usage of it thru the UI 
forces you to fully allocate (as compared to sparse allocating) your subnets, 
basically the same way subetting is taught in base level networking 
certifications. This makes finding the un-used subnets very easy.
http://sourceforge.net/p/subnetsmngr/wiki/Home/ 


NIPAP allows you to do the same as well, but will let subnets be sparse 
allocated, so you won't necessarily have pre-created them waiting to be used 
later on. 
http://spritelink.github.io/NIPAP/ 
NIPAP also has a nice CLI interface.

Both are also open source, full v4/v6.

Re: CIDR Utilization

[joel jaeggli]

most reasonable ipam tools will track or express unallocated vs
allocated space.

netdot has a lovely address-space container/block view for managing free
vs allocated space

It is rather nice that IS-IS does not require level-2 to be
contiguous, unlike area 0 in OSPF.  It is a valid topology
in IS-IS to have different level-2 areas connected by
level-1 areas, though you do have to be somewhat
careful about what routes you propagate into-and-back-out-of
the intervening level-1 area.

But other than that, yeah, the two protocols are
pretty much homologous.

Level 3 issues in Chicago

[Randy Carpenter]

A network that we manage is having trouble getting to several sites. The common 
point of failure appears to be Level 3 in Chicago. Connections work fine from 
our direct upstream, so it appears that Level 3 is not allowing traffic sourced 
from the net block in question. Can someone from Level 3 ping me off list?


thanks,

I found Route Leaking in IS-IS to be a moot endeavour because if one
wants to keep absolute routing inside the IGP, you'll want to have the
core and Loopback interface addresses in the IGP, particularly if you're
running an MPLS network.

In such a case, the only real gain you get from multi-level IS-IS is a
little quietness re: the LSP's being propagated within a particular
Level-1 Area. However, things like PRC (Partial Route Calculation) and
iSPF (Incremental SPF) help a lot here when you have a flat Level-2
IS-IS domain.

Re: Satellites and submarine cables

[Sean Donelan]

Dyn Research, Doug Madory, has a good blog post looking at the physical 
threats affecting submarine cables; as well as covering recent historical

submarine cable outages due to human action.

http://research.dyn.com/2015/10/the-threat-of-telecom-sabotage/

And also a very nice infographic by Caroline Troein, Tufts University, 
show global submarine cable vulnerable points.


https://sites.tufts.edu/gis/files/2014/11/Troein_Caroline.pdf

Overall, Internet architecture has demonstrated resiliance to physical 
layer disruptions, but it has not proven as resliant to logical layer 
disruptions.

This seems to be a case of "I know you can see me, and I can see you."

Its not new. Multiple countries have demostrated submarine and satellite 
capabilities over the decades ... more submarines than satellites. But 
generally everyone has more to lose than gain.  What is different is the 
increasingly public rhetoric.


Occasional satellites or submarine cable disruptions haven't had long term 
impact on the US mainland due to US connectivity options. Carriers serving 
the US mainland regularly have outages and repair submarine cable and 
satellite problems. But countries with less connectivity options could get 
pushed around more, along the lines of "Make him an offer he can't refuse." 
Some of the public rhetoric may be for allies.
