Semi-Annual 'System Status Page' solicitation
by Jay Ashworth 10 Feb '11

10 Feb '11

If you work for a backbone, content, access, or service provider, and you know that your company has a publicly accessible System/Service/Network Status Page available on the web, we'd love it if you'd add it to the Outages Dashboard, at http://wiki.outages.org/index.php/Dashboard If you have an account on the wiki, you can add it directly; if not, you can add it to the associated Talk page, or email it to me off list, and I'll be happy to add it for you. You're perfectly welcome to add any other pages we don't have listed as well, as long as they're publicly accessible. This was a recording. Cheers, -- jra

BCP38 considerations in IPv6
by Ryan Rawdon 10 Feb '11

10 Feb '11

Hello NANOGers - What considerations should be made with respect to implementing egress filtering based on source IPv6 addresses? Things like allowing traffic sourced from fe80::/10 in said filters for on-link communication (for the interface that the filter is applied to). Is there anything else that should be taken into account while implementing BCP38 egress filtering in IPv6? Ryan

ARIN and IPv6 Requests
by ADWebb＠dstsystems.com 10 Feb '11

Why does ARIN require detailed usage of IPv4 space when requesting IPv6 space?

Self-referential whois queries
by Rubens Kuhl 10 Feb '11

10 Feb '11

I'm noticing an increase in getting "query rate exceeded" at whois services that might be connected to a symptom described by ARIN at NANOG 48/ARIN XXV and ARIN XXVI where machines ask for the whois record of their own IP address. Are there any clues of what is causing this ? Rubens

Comcast BGP issue?
by Wallace Keith 10 Feb '11

10 Feb '11

Not quite sure what the issue is, but I suspect Comcast announcements are not quite right? Trying to get from Verizon Business to a Comcast address in NH (on 75.15.64.0/18), and it's going through San Jose. Anyone else having similar issues or suggestions?

Ipv6 addressing for Core network
by Vikas Sharma 10 Feb '11

10 Feb '11

Hi, I am looking for the recommendation for core interfaces IP addressing schema for Ipv6. Some different views are (PE- P - PE, point to point link) as below - 1- Use Public Ipv6 with /122 and do not advertise to Internet 2- Use Public Ipv6 with /127 and do not advertise to Internet 3- Use Unique local ipv6 address 4- Use Public Ipv6 with /64 Also I am interested to understand the impact on TCAM ... Regards, Vikas
