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
Windows will just populate the reverse zone as needed, if you let it, using dynamic update. If you have properly deployed BCP 39 and have anti-spoofing ingres filtering then you can just let any address from the /48 add/remove PTR records. Other OS's will follow suite. Alternatively you can delegate the reverse for the /48 to servers run by the customers.
