Hi list,

this is my first post, so be nice. :)

Wondering about IPv6 deployments to end-users, imagine we deploy a full /48
address to each client.
How is the reverse DNS for each possible IPv6 address going to be?

Nowadays I'm used to do IPv4 reverse using old Class C, which has (up to)
256 entries. Are we really going to make reverse DNS entries for each of
those 2^80 addresses? Or going to deploy rDNS only at the PtP links and
relevant servers?

Kind regards,
Felipe
