Automatic DNS updates when DHCP assigns a new address

I have a DHCP-assigned IP on the Internet. I would like to host a web
server, however this is not a good idea since DHCP address can change.
I don't have an option to use static IP (provider difficulties
*sigh*). What is the best way to make sure I get the most out of it?
My thoughts:
- DNS propagation will take days to be good if DHCP changes a lot
(i.e. more then once in a month - quite possible)
- I don't know how to update DNS even if this happens (is this
possible with "regular" registars e.g. godaddy.com or such?)
- As the really last resort, using another web site with a static IP
is possible, then redirect to my current IP (some PHP would probably
do the trick)

Did any of you folks have and solve such a problem?

Yep, dyndns is great, You can pay for a 'Custom Domain' or a free
subdomain and just CNAME your domain to that free url.
