Heres an example:
[alex at moe alex]$ ipcalc --network 172.16.18.123 255.255.248.0
NETWORK=172.16.16.0
This is an IP in the range I am trying to set up - hence the zone I am using
is 16.16.172.in-addr.arpa.
---------------------------
zone "16.16.172.in-addr.arpa" IN {
type master;
file "db.172.16.16";
allow-transfer { none; };
allow-update { none; };
};
---------------------------
[alex at moe alex]$ cat /var/named/db.172.16.16 |more
at SOA moe.foo.com. root.foo.com. (
3
10800
3600
604800
86400 )
IN NS moe.foo.com.
123.18.16.172.in-addr.arpa. IN PTR host-18-123.foo.com.
-----------------------------
This message appears in the messages log on zone reload:
Nov 29 10:51:18 moe named[5277]: db.172.16.16:12: data
"123.18.16.172.in-addr.arpa" outside zone "16.16.172.in-addr.arpa" (ignored)
I *think* I somehow need to tell it the netmask, but I can't figure out how.
