Dynamic IP.. domain name and stuff :)

[Guv]

Here's what I want to do, but can it be done?

My internet connection has a dynamic IP address, it's changing daily. It would be very useful to be able to remotely log into my pc from when I'm not at home but this is proving very very difficult with the IP changing all the time.

So, is there a way to have a domain name pointing to my home PC (ie. my home IP address) but with some way to update the IP address automatically when it changes to the domain settings?
(I hope that makes sense)


thanks
