[Pdns-users] in.addr-arpa delegation

[Max Clark]

Derrik,

While RFC 2317 covers classless delegation for subnets smaller than a
/24 it does not cover delegation for subnets equal to or larger than a
/24. If I have a /20 assigned from ARIN that points to my nameservers
- how do I delegate a /24 to my customer's nameservers using powerdns
without using the classless delegation approach?

i.e. if the subnet is 192.168.1.0/24 I would like the customer's name
servers to see the request as 1.1.168.192.in-addr.arpa and not
1.0/24.1.168.192.in-addr.arpa.

I know this is possible with an ARIN SWIP of the IP space - I am
trying to avoid doing this with SWIPs.

Thanks,
Max
