Did we all enjoy our leap second? We had an extra second of drinking
or sleep or whatever last night.
If anybody has ATT residential DSL and wants to use their IPv6
implementation I think you can. I am.
They are using 6RD, which is a 6in4 tunnel using their own tunnel
endpoints (border router) and a special IPv6 addresses range. There are
tools, that may or may not help, at https://code.google.com/p/6rd/
You need your address prefix plus netmask/prefix length and you need
the address of your border router. Your assigned address is the prefix
plus your IPv4 address. If you have a static IPv4 you have a static
I put my DSL modem in "bridge" mode and run the PPPOE on my router.
The 6RD tunnel runs on my router.
Basically, 2602:300::/28 (6rdPrefix/6rdPrefixLen) and 126.96.36.199
(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).
For fun this gives all the machines on your network globally addressable
addresses with all of the security paranoia that brings.
Since we all have different modems, routers, etc. I assume that
specifics about what I did aren't helpful. I would be interested to
hear how it works for others.
