As far as DNS is concerned, it's fine.  DNS doesn't know anything about
networks, it just translates names to addresses.  If you create two A
records for linux.home.net, you'll get round robin between them.

You also need to add the zone to the named.conf file, so named will know to
read that file:

zone "1.168.192.in-addr.arpa" {
  type master;
  file "named.192.168.1";
};
