How static is the IPv6 prefix delegation?
I haven't been able to find anything paticularly conclusive on this.
If I request IPv6 delegation via DHCPv6 from the Comcast router, how static is this? Completely?
What about the IPv6 addresses my router receives on its internal interfaces for these prefixes? Are these completely static? For example, if interface "lan0" is set to have prefix id "0", will interface lan0 _always_ receive the same static IP?
What about delegation for reverse IPv6 DNS zones? Is requesting rDNS records through the forums the only way or is delegation possible now?
