A simple scheduled portscan by the ISP on its customer's IP addresses 
would tell them if common (and even uncommon) ports are being used. It 
would probably be straightforward for some script wizard to make a 
script to change the IP if open ports are found.

The way around this is to use one of the dynamic DNS systems around the 
'net. DynDNS.org is a great one - just do a search for "dynamic DNS" on 
your favourite search engine to find others.

Hope that's of use,

PS Here in Aus, I've had the same IP with our cable provider (Bigpond) 
for close to 2 years, even though it's officially dynamic. That's even 
with a move across town and numerous power resets on the cable modem. 
They frown on people assigning static IPs in their TCP/IP settings, even 
if it's the same IP which has been distrisbuted via DHCP. And we can't 
pay for a static IP, not that it's mattered for ages.
