Any suggestions on what to tell ATT to get IPv6 added to a current account and upgrade a 2wire router to 4wire with halfway decent performance and capability? Any and all help would be appreciated. Tom
If ATT is still using 6rd then you don't need a hardware change to use it. 6rd is like a 6to4 tunnel with special features. You can run it on your router or other machines. Openwrt supports it. Here is a brief how to, google for more help: http://www.litech.org/6rd/ For ATT, basically, 2602:300::/28 (6rdPrefix/6rdPrefixLen) and 12.83.49.81 (6rdBRIPv4Address, which is an anycast) is all you need to get it running. IPv4MaskLen is 0 (use the whole IPv4 address within IPv6, but notice that due to 6rdPrefixLen being /28 (instead of the more conventional /32) you have to do some one-nibble shifting, but the plus side is that you do get a /60 in the end). If your IP number is not static then your IPv6 address won't be either. Of course you could always try 6to4, where the prefix is 2002::/16 and the anycast relay router is 192.88.99.1. This will work if ATT resolves the anycast address. Or you could set up a Hurricane Electric 6in4 tunnel. So, with ATT residential, I think you get 3 half assed choices, 6rd, 6in4 and 6to4 (if they support it). Bill
