the cable-modem won't care, but there's no other way to get your IP
than with DHCP. Statically configuring for indefinite periods of time
would be a very bad idea.

and more imporantly than you finding out what the new one is, is the
issue of you finding out that the old one is not valid.. otherwise you're
very likely to continue to use an IP that has been legitimately
reassigned via dhcp to another user. theoretically bad
news. (realistically you only get renumbered when segments split, so
the new box with your old number would be on a differently routed (and
legitimate) segment and you'd pretty much be blackholed, so the damage
is mitigated)

nonetheless, the terms of service are very clear about it being a DHCP
driven service and you need to be able to live by the terms of the
leases acquired that way.

if you're running an old libc-5 system, I'm sure you'll receive lots
of advice to just copy the data off this box and put on a more modern
installation. Even if just for security reasons if you're going to put
the box on net. (and firewalls aren't security cure-alls..)
