hello, does anyone have any experience with peering in S. America? I am looking to move a lot of data between NewYork/LA and a few south american countries and looking for some ISPs that have reliable peering into those countries. Any recommendations would be appreciated. The one i did find was Terremark, but no others yet. thanks Adam

IPv6 Addressing Plans
by michael.dillon＠bt.com 28 Dec '07

28 Dec '07

During all this discussion about v6 and home networks, has anyone had a look at ARIN's IPv6 wiki, in particular at the IPv6 Addressing Plans page? http://www.getipv6.info/index.php/IPv6_Addressing_Plans Although it still has the original note about being a bit of a strawman proposal it has incorporated a lot of input from earlier discussions on the NANOG list and the IETF list. Item 12 on that page applies directly to home networks: 12. All customers get one /48 unless they can show that they need more than 65k subnets. -Host count is irrelevant. -Do not assign from PoP aggregates -Carry customer networks in iBGP -Aggregate only in eBGP -If you have lots of consumer customers you may want to assign /56s to private residence sites. Aside from snarky remarks about the IETF, does anyone have anything substantial to contribute that isn't already on that page? If you want to you can use the "discussion" tab on the wiki to comment. --Michael Dillon

looking for help for the statistics data on spoofing attack events on Internet
by yangyang. wang 26 Dec '07

We are conducting an experiment to evaluate IP source address spoofing attacks on Internet and want to collect some statistics data or report about it Which organization or research group could support some statistics data, report or hints on the spoofed IP source address attack events, DNS spoofing events, router forged update events on the whole Internet or regional network for research analysis? Best wishes!

If people are supposed to have a /48 then the allocation rules should say that's what they will get. It may be xmas but it's not wise to rely on the benevolence of ISPs brandon
