Yesterday my ancient TimeCapsule was misbehaving. Our network connection still worked, but nothing else did. Because of its age, I decided it was time to retire it from being our home’s gateway to the internet.
I reconfigured my v6 Airport Extreme and connected it to the shiny new IPv6 enabled cable modem that I installed in 2012. I had been anticipating that eventually IPv6 would arrive. My 10 year old Motorola Surfboard 5100 was retired because it didn’t support IPv6. After rebooting the Motorola SB6121 cable modem, the IPv4 network came right up. I went in to set up IPv6 tunneling and noticed I had native IPv6 addresses assigned!
Apparently Comcast rolled out IPv6 in Washington in Sept. 2013.
