One comment here. You should be using an "experimental" network per RFC
1597, not just any old network. There is a legal Class A network, one or
more legal Class B networks, and there are several legal Class C
networks. I don't recall offhand the legal class A network, but I don't
think it is 90.0.0.0. One of the legal class C networks is 192.168.1.0,
which is what I use.
Aside from the general niceness of complying with the traffic rules of the
Internet, there is another reason to use one of the experimental
networks. Suppose for a moment you used 15.0.0.0, which happens also to be
HP's Class A network. Packets from your network addressed to any of HP's
machines would never leave your network. This would make it difficult for
you to send email to someone at HP.
It would also leave you open to violating a fundamental rule of the
Internet: no two machines may ever have the same IP address. Violating
this rule will 1) have one or more sysadmins elsewhere on the net very
annoyed at you, and 2) give both you and those sysadmins fits trying to
diagnose various mysterious problems.
Eric: I'm not trying to publicly toast you, I just want to make it clear
for other folks' benefit.
