Well, not to get pedantic, but...oh, WTH, yes I will.
It doesn't matter at all what you use internally as long as it doesn't get
_out_ of your internal network. Use Lucent internal network addresses, if
you wish. Especially if you use something like ppp and IP Masquerading
to get to the net, there will never be a problem.
BUT. It's not a _good_ idea. You never know when you may 'leak'. Plus, RFC
1918 defines selected ranges of Class 'A', 'B', and 'C'network addresses that
are reserved for private network use. These, incidentally, can be--and are--
looked for by active network elements to prevent their proliferation on the
'Net.
Another suggestion--why not stay with Class 'C' network addresses? That's
most commonly what you'll encounter in the "real" world--or at best, Class
'B' addresses--and it'll be more familiar to you WRT netmasks, etc., if you
play in the same sandbox.
$0.02, YMMV. Have fun.
