NIS domain name has nothing to do with DNS.

If you don't know about it, just forget it - you don't need it.

NIS is just a replicated database of tables like hosts, passwd, group,
netgroup etc. If you have a few Unix boxes in a LAN, you would want to
have the above data synchronized, i.e. have the same user/passwords,
hosts etc. NIS allows you to maintain this on one host, have it
replicated to slave servers and used by many machines.

The overhead of maintaining NIS is too high to consider it with less
than ten hosts in my view. In a corporate environment my experience is
that it is one thing which tends to bury itself deep into the
infrastructure and is difficult to replace - especially when one has
to maintain 10 year old systems with long-unsupported OS... So stear
clear from it.

Sun brought replacement for it - NIS+ - which I have to admit I have
never used. If you need to have that sort of information network
available, consider LDAP.
