It's not clear to me whether you *just* changed the subnet mask or you actually
changed the IP address of the ethernet interface. If you changed the IP address,
then unless you have reverse lookup set up for the new address, nslookup is going
to bogusly fail. Real lookup tools like "dig" however, should still work,
regardless of whether the nameserver address can be reverse-resolved or not.

If all you changed was the subnet mask, then I'd say this is probably a deeper
networking problem rather than a DNS/BIND problem _per_se_.

Oh, and don't use an illegal B class. Use another slice of 192.168/16, as Mathias
already suggested.
