The gateway and my dozen+ devices do not seem to have any issues getting dynamic IPv6 addresses, and since most are Apple, IPv6 is the prefered connection method. As an "end-user", I don't know why Comcast has chosen to give my network MORE address space; like 1800000000000000000+ addresses wasn't enough; they've given me 295000000000000000000+ addresses.
In reality, for an end user network, /96 is plenty with 2^32 addreses, and /112 is even more reasonable with 2^16 addresses; especially when you compare it to the default settings on every consumer IPv4 gateway with 2^8 addresses.
