AW: Cogent/Level 3 depeering
by John van Oppen 05 Oct '05

05 Oct '05

I think in all the recent cases, cogent ended up buying transit from verio. That was the case for access to AOL and Sprint when I turned off my cogent feed a week ago. I think that is also what they did with france telecom but I am not sure on that one as I never checked (I had other transit).

Thanks!

TLD anycast clouds?
by Steve Gibbard 05 Oct '05

05 Oct '05

I'm attempting to come up with a list of all the top level domain DNS servers that are anycasted. I already know about the anycast clouds run by PCH, Neustar, Verisign, DENIC, and UltraDNS, and .mx appears from traceroutes to be anycasted as well. (I know about the anycasted root servers as well; they're out of scope for this question...) Are there others that I'm missing? Thanks, -Steve

(What If?) ccTLD Delegation Question
by Joe Johnson 05 Oct '05

05 Oct '05

Call it Monday Boredom, if you will, but a funny DNS question just popped into my head: if I were to, say, win the lotto and buy my own Island (which, of course, would technically be its own country), would I be able to receive a ccTLD for said island nation? Kind of like .joejohnsonisland or .jji? If so, would the DNS have to be actually contained inside of said island? I think not, as it was mentioned earlier that .iq was run from Texas, but it's always good to ask. Joe Johnson joe(a)sendjoeanemail.com

GigE Peering Router
by Network Lists 04 Oct '05

04 Oct '05

Hello, I was looking for some opinions on Cisco vs. Foundry (specifically Cisco's NPE-G1 vs a NetIron 4802). The application is mainly content delivery - outbound heavy traffic with an emphasis on quality of delivery. Basically I'm looking at the 4802 because we're able to provision GigE for all the providers, so we don't really need an architecture that can support OC-type interfaces. The size is also attractive for some of our smaller PoPs. I'm also intereted in failover/hot-standby capabilities on the Foundry as we have had much experience with them. Best, Lance

Re: Overview: (What If?) ccTLD Delegation Question

Given the ongoing flux in national boundaries and identities, this topic is highly appropriate and the contributors gave well spoken input. Thank you. Cutler At 10/3/2005 05:13 PM -0500, Joe Johnson wrote: So, basically, following the instructions at http://www.iana.org/cctld/cctld-establishment-procedures-19mar03.htm, I need to be sure I legally acquire the island from a nation for the express purpose of running my own country (the sales agreement says I am no longer part of them). After I establish my national government (I held an impromptu straw-poll in the office, and we chose "Joetopia" as the name of my island nation), I need to petition the UN to be recognized as a nation and be listed in their report. After that, I automatically get a 2-letter nation code and can petition ICANN for a ccTLD of my 2-letter code. I can then choose to run .jt (or whatever my ccTLD ends up being) from any place I desire. Well, thanks for all the help everyone. Hopefully it broke the day's monotony for some of you. Now I just need to sit back and wait for those lotto winnings to roll in (ha!). Joe Johnson joe(a)sendjoeanemail.com P.S.: Don't worry, I'll be sure to have plenty of redundancy in my DNS (physically separate NS's, multiple DNS servers, power, etc.) and I won't brook no spammers. Not from my .jt ccTLD! - James R. Cutler james.cutler(a)consultant.com
