How to generate authoritative DNS64 reverse zone

[Alberto Colosi]

Hi, is hard an ISP give to you a reverse lookup zone


first of all , is needed you to "own" all zone (ipv4 , all C class) for example.

as second thing, is really hard to move definitions on TLD like ripe , arin, apnic or others ....

is more possible ISP give to you (if first line is true)  controll of reverse zone and ISP transfer from you reverse zone definitions without involving ripe/arin/apnic/...


I spoke as I was in the need with an ipv4 reverse zone and ISP only accepted on that way.


if you don't "own" entire zone , is no way to have this from your ISP.


Remember ipv6 or ipv4 reverse zones are queried only if right referenced on ripe/arin/apnic/... or your ISP transfer from you the ipv6 zone.


repeating if you not "own" entire zone , ISP never will accept to move to you or to transfer from you the zone as other IP don't belong to you

Subject: How to generate authoritative DNS64 reverse zone

Hello,

Suppose that I have a NAT64 prefix 2001:67c:2b0:db32:0:1::/96 and a
couple of DNS64 resolvers that use it. The resolvers will also generate
nice CNAMEs that point to in-addr.arpa for that prefix. This is nice.

But other resolvers in the world won't do that, so I'd need to have a
real reverse zone for this fantastical NAT64 prefix for their benefit.
But if I configure a DNS64 prefix on an authoritative server, it will
start messing with my normal zones too, won't it?

So how do I configure Bind9 to generate one authoritative DNS64 reverse
zone that contains CNAMEs to in-addr.arpa, but otherwise not mess with
anything?

Yours,
