Services for "Dynamic DNS" may be relevant to your question:

The idea is that your computer would tell the dynamic DNS system what
its dynamic IP address is, and then the system would forward other
users to your computer.  Of course, this means that you have to keep
your computer up and running.


For anything serious, I'd probably try to have a hosted server
somewhere with a static IP address.  Amazon EC2 does stuff like this,
as do other web hosting providers.
