I have a /48 native IPv6 prefix routed to my home lab. I come back from IETF, and Firefox 3.0.6 is hanging accessing www.ietf.org on my duo-stack Centos 5.2 laptop. I do a ping6 and can get to www.ietf.org, so it is not a routing problem. I run wireshark and I see IPv4 and IPv6 tcp sessions. In the end I have to disable IPv6 in Firefox to get to the ietf home page. Doesn't see right, I had no trouble with this at the meeting and all I did was suspend my system to go home. I rebooted here (horrors, rebooting a Linux system) jsut to see if there was something hanging around from ietf. _______________________________________________ Ietf@xxxxxxxx https://www.ietf.org/mailman/listinfo/ietf
