That's how I suspect it will go with my current service.  I'm just wondering
how long the expiration time is set.  I use the Linksys router, so as long
as my power is on at home, my connection will be active.  It claims the
expiration time is 4 days, so I'm going to shut it off and find out in a few
weeks.

My service uses DHCP, but I have found only two times when the IP over 3
years has changed :
1) they "upgraded" my modem to a new one
2) when I swapped the NIC

No other times...

I'm not sure how the rest of the cable modems work, but with @home
(obviously this doesn't matter much now) you basically get a static IP
anyway.  Sure it uses DHCP, but does that matter when it never expires?
With our new cable company's service (just got switched to Insight
yesterday) it appears that the DHCP is based on the MAC address (@home
used the hostname apparently).  So I'm guessing that as long as I don't
switch my Ethernet interface I'll have the same IP address.  But I'm
going to play with that first.  I'm also going to shut everything off
when I go on vacation in March to see if it expires and gives me a new
one.

Anyway, what I'm saying is that you may be able to just use the IP you
have now as if it was static.  Just test it out first and see how often
it changes.  That's what I do, although I have no mail server running.
Just a web/FTP server to play with.  Although my friend, who's with the
same ISP, does have Exchange running just fine.

I want to setup a Home Office and I have a Cable Modem which they tell
me cannot guarantee a static IP address.  Our mail records are hosted by
an ISP.  Is there a way for me to setup an Exchange 5.5 or 2000 server
to receive and send mail in this configuration?  Where and what do I
have to configure in order to have this work correctly?
