The module now implement a scheme to delegate sub-net reverse
mapping. This is new and experimental. When you create a reverse
zone,there is an extra field to enter the sub-net. You enter the last
digit of the network address and the number of significant bit. From
there, Linuxconf will know how/when to update this reverse zone.
For example, if you have the sub-net 192.168.1.64/25184.108.40.206
you would enter:
Network number: 192.168.1
Subnet x/y : 64/26
The zone created will be called 64/220.127.116.11.in-addr.arpa. The owner
of the zone 1.168.192.in-addr.arpa will have to set a bunch of cnames
to point his DNS to yours.
