  Some things that haven't been mentioned:

  As long as you keep your DHCP client active, it should keep renewing
your lease.  So your IP address should remain relatively unchanging.
Unless Comcast is renumbering your area, in which case you're going to
loose the IP address regardless of lease duration.

  Use a dynamic DNS service to make it possible to look-up your
current IP address from the outside world.  DynDNS gives you one free
A record, and even notifies you if your DDNS client doesn't update it
when it should.  That's what I've been using for years now.
