Windows 7: Establish Remote Desktop Connection using Domain Name, rather than IP?

I'm currently accessing my PC through Remote Desktop Connection from my college library to show my project team-mates the progress of the project. To get the IP address, which is dynamic, I always do some circus like

1. I leave GMail account open here
2. See the concurrent connections of GMail account in the library
3. Then use that IP address to establish the connection

That's a pretty long way, right? RDC client in Windows gives domain names and sub-domain names as examples along with an IP address. So, is it possible to use a domain name - or a sub-domain - rather than IP address to establish a Remote Desktop Connection to my PC?

If yes, please help me how can I configure.



NOTE: I use some third-party service to point the domain to my computer with changing IP address. So you may assume that I have a static IP address for instructions.
