VS>> This is very interesting. Why "prefixlen 60" on the LAN?
SS> Perhaps - an educated guess here - Comcast's provided gateway has, SS> potentially, 4 internal LAN interfaces. It could be configured with a SS> 5GHz WiFi subnet, a 2.4GHz one, the GbE ports, and a 'Xfinity Home' SS> port. I haven't investigated what the "Home" port is used for, but SS> that may explain the breaking down of the /64 to /60. Again, just a SS> theory.
Whatever Comcast's intentions, are you sure that a LAN with a prefixlen different from /64 will work properly? Will a non-standard prefix not break SLAAC and other things?
This is where my theoretical knowledge is lacking, but I've always been warned against using anything different from /64 on a LAN segment.
