What causes 'Can't find server name for address' error?

You should be able to see a lot of things wrong. First, an IPv4 octet
is only 8 bits, so the maximum possible value is 2^8-1, or 255. Thus
both 333 and 444 is invalid.

Also, how do you think BIND should resolve something it has no idea
about? I don't have the docs easily at hand right now so I'll leave
whether specifying all four octets in an in-addr.arpa zone is valid or
not to someone else to answer; but you definitely have to put in a
record for your IP.

Try adding this to your 111.222.333.444.rev, and use valid IPs:

	@ IN PTR mydomain.com.

This should be documented in the ARM, as well.
