Im running FreeBSD 6.2 RELEASE on the tunnel endpoint and it acts as my v6 router. This is my rtadvd.conf file contents: rl0:\ :addr="2001:4978:12e:a::1":prefixlen#64: On my xp machine I have always had to manually config a v6 address but the route was done automatically. This is no problem for me. However this week I noticed that the xp machin is getting two more address all by itself with no way to delete them it seems.

The next two, Temporary and Public, I have no idea why these just all of a sudden started showing up. There have been no changes in my router configuration in a 8 months. As far as windows goes... I thought maybe a recent M$ update might have caused it but I can't find anything. Any ideas as how to delete these and prevent it happening in the future? Thanks in advance for any assistance. :)
