The suggestion of dynamic dns is probably the best one. Check out
dhis.org.

If your ip is not in use, the lease has _not_ expired, and there are no
free ip's to give out, a dhcp server may use your ip. We have a week or
two for our ip here (I guess the client sends a renew request every few
hours so it knows the client is alive). However, when my ip would change
over the weekend, I could tell they ran out of ip's. If we aren't short
on ip's, my address will stay for a few months (summer and winter break).
