Re: [cobalt-users] RaQ4i HowTo do RFC2317 reverse DNS delegation (more details)

["Gail Waugh" <gail@xxxxxxxxx>]

 Per RFC 2317 we do the following for an example delegation of a /28
netmask 255.255.255.240

We have delegated the reverse for your netblock to your two name
servers
IPs 1.2.3.32/28

@ IN SOA ns1.delegator.tld. hostmaster.delegator.tld. (
                         2000082300
                         7200 3600 604800 86400)
         IN      NS      ns1.delegatee.tld.
         IN      NS      ns2.delegatee.tld.
 ;
 32-28   IN      NS      ns1.delegatee.tld. ; customer master
 32-28   IN      NS      ns2.delegatee.tld. ; customer secondary
 ;
 32      IN      CNAME   32.32-28
 33      IN      CNAME   33.32-28
 34      IN      CNAME   34.32-28
 35      IN      CNAME   35.32-28
 36      IN      CNAME   36.32-28
 37      IN      CNAME   37.32-28
 38      IN      CNAME   38.32-28
 39      IN      CNAME   39.32-28
 40      IN      CNAME   40.32-28
 41      IN      CNAME   41.32-28
 42      IN      CNAME   42.32-28
 43      IN      CNAME   43.32-28
 44      IN      CNAME   44.32-28
 45      IN      CNAME   45.32-28
 46      IN      CNAME   46.32-28
 47      IN      CNAME   47.32-28
 
The delgatee will need to set up a 32-28.3.2.1.in-addr.arpa zone on their
server with the PTR records listed above.
