IPv6 Prefixes and Comcast Business
Why does Comcast give out /56 prefixes when /64 is what is standard via the IETF? Comcast is actually giving me 8 more address bits for a total of 72 for me. Comcast has eaten into their own subnet address space by doing this. It is only creating confusion and will eventually have to be fixed (at whose cost?). I have the ability to address 4.72 x 10^21 hosts (a bit much)...... Your Cisco gateway/NAT/firewall/whatever is confused in this process (it's not a router).
Are those extra 8 bits for me to allocate via my routers (if I were a large company?)? If so, how?
