Creating an IPv6 addressing plan for end users
by Nathalie Trenaman 28 Mar '11

28 Mar '11

Hi all, In our IPv6 courses, we often get the question: I give my customers a /48 (or a /56 or a /52) but they have no idea how to distribute that space in their network. In December Sander Steffann and Surfnet wrote a manual explaining exactly that, in clear language with nice graphics. A very useful document but it was in Dutch, so RIPE NCC decided to translate that document to English. Yesterday, we have published that document on our website and we hope this document is able to take away some of the fear that end users seem to have for these huge blocks. You can find this document here: http://bit.ly/IPv6addrplan (PDF) I look forward to your feedback, tips and comments. With kind regards, Nathalie Trenaman RIPE NCC Trainer

The growth of municipal broadband networks
by Paul Graydon 28 Mar '11

28 Mar '11

http://arstechnica.com/tech-policy/news/2011/03/133-us-cities-now-run-their… Ars Technica has a short article up about the growth of municipal networks, but principally a nice little 'hey check out this website' (http://www.muninetworks.org/communitymap) The whole scenario around municipal broadband networks in a hopefully unbiased nutshell: Increasing numbers cities and counties seem to be getting frustrated with what they see as the lack of progress in broadband speeds from their incumbent provider(s) (even after incumbent provider(s) have been approached requesting faster speeds) and are deciding to do it themselves. Chattanooga, Tennessee has become the poster child for the idea, able to offer 1Gbps to users and businesses at competitive prices ($150 pcm.) I'm curious how the feeling is on NANOG about shifting such provision towards municipal instead of corporations? I guess a rough summary of the competing views I've heard so far are: + It's fair and valid competition in the market, which is encouraging major ISPs to innovate instead of resting on their laurels and trying to do the bare minimum necessary to maintain their position and profits, an attitude that is stifling other economic growth? - Local government is sticking its nose in where it shouldn't, providing unfair competition and stifling normal market processes. Municipalities are operating on the false belief that large bandwidth will automatically bring silicon valley to them, without understanding the bigger picture. That it's time, money and resources better spent on tax incentives or other means of encouraging businesses. Paul

Using Region-X assigned IP space in Region-Y?
by Mark Leonard 28 Mar '11

28 Mar '11

Hello NANOG'ers, This is a question that popped into my mind recently. So far my google-fu has not turned up anything of use. Imagine a company that has an RIR-assigned IPv4/23, and has it subnetted into a pair of /24's so that they can have replicated datacenters in two different geographical locations each running its own BGP infrastructure (using the same ASN). As far as I can see, this is all fine and good assuming that these two sites are in the same RIR's domain. Is it possible/allowable to move one of these datacenters to a different geographical region with a different RIR and keep using the same two subnets, or will a new /24 need to be requested from the new RIR? If there's a book or reference that answers this question, please let me know - I'm willing to do as much research on my own as I can. Thanks!

characterizing BGP updates (research topic?)

I am, however, certain that other people could suggest even better research topics. Good research topics are in demonstrably short supply among networking grad-students, so if y'all want to be helpful... I'm currently looking for data characterizing BGP updates. This page calls out 'bad' guys: http://bgpupdates.potaroo.net/instability/bgpupd.html but I haven't found anything yet which defines the terms or methodologies used. Is there a key for this page somewhere? Are there similar data sources for BGP update stats that go into more detail? I'm personally interested in being able to tell the difference between new announcements/withdrawals of a prefix to the Internet as a whole (insufficient redundancy?) vs. changes in best path (next hop). If I can get my hands on raw BGP update traffic info, I would even consider taking a stab at doing the analysis myself. Pointers to data/previous results (as well as comments on why this is a stupid question) are welcome. Thanks, Bill Bogstad

We are looking to install a few repeaterless undersea fiber runs <100miles at depths of no more than a few hundred feet. Does anyone have any leads?

Google security
by Christopher Wolff 27 Mar '11

I have a client that acquired a domain name and affiliated company as a product of lengthy and extremely turbulent litigation. The client believes (and I have found evidence to suggest) that the previous owner is somehow interfering or interacting with the new owner's Google Analytics/Webmaster Tools/Places/Adwords accounts. Since I am representing the new owner, I am trying to find a forensics analyst or clueful contact at Google to act as an independent third party to 'certify' that in fact the previous owner is or is not interfering in the new owners Google Accounts. I've followed the standard protocol, i.e., post your question in the Google forums and wait for a response. To date the single response I've received is "change your password" which wasn't what I had in mind. If that contact or independent third-party forensics expert exists, I'd greatly appreciate any advice you can provide. Best regards, Christopher

Which internal WAN protocol?
by Richard Dunn 26 Mar '11

26 Mar '11

I would appreciate it if list members could tell me which WAN routing protocol(s) you use and why? If you have changed from one to another what did you change from to and why did you make the changeover? If you use multiple protocols or same protocol redistribution for specific or other reasons if you could explain why I would appreciate it. On or off list as you prefer. Thank you. Richard

Nortel, in bankruptcy, sells IPv4 address block for $7.5 million
by Eugen Leitl 26 Mar '11

http://blog.internetgovernance.org/blog/_archives/2011/3/23/4778509.html Nortel, in bankruptcy, sells IPv4 address block for $7.5 million by Milton Mueller on Wed 23 Mar 2011 10:30 PM EDT | Permanent Link | ShareThis Wake up call for our friends in the Regional Internet Registries. Nortel, the Canadian telecommunications equipment manufacturer that filed for bankruptcy protection in 2009, has succeeded in making its legacy IPv4 address block an asset that can be sold to generate money for its creditors. The March 23 edition of the Dow Jones Daily Bankruptcy Report has reported that Nortel's block of 666,624 IPv4's was sold for $7.5 million - a price of $11.25 per IP address. The buyer of the addresses was Microsoft. More information is in its filing in a Delware bankruptcy court. Now the interesting question becomes, does the price of IPv4s go up or down from here? As the realities of dual stack sink in, I'm betting...up.
