Re: [IPv6] Evidence of Comcast IPv6 CPE Dual Stack (CPE and CPEP

1) Dallas, PA
2) Mikrotik RB750G w/ version 5.19 installed.
It's been getting a prefix since the end of June but I couldn't figure out what to do with it until this past week (Mikrotik's require more configuration).

Hello.

Does anyone know if the Comcast CMTS in Atlanta is capable of IPv6? Got the new firmware update for the Moto SB6120 yesterday and for a moment, the configuration page said the modem was in IPv6 mode. But now, it's back to IPv4 mode.

Does anyone know if the Comcast Atlanta CMTS is capable of IPv6? I tried that lookup of the MAC address and it seemed to indicate a brand that was not Cisco. So, I thought it would get IPv6 soon.

Thanks.

I have a WNDR4500 but it's not getting the IPv6 address correctly...at least when I remove the 6to4 setting, my browser tests all fail on the IPv6 tests.
