Hi,
Let me see if I can help you on this.
You have an option in Godaddy to map your domain to the IP. By doing this
when I go to yoururl.com --> resolved to -->
http://1.1.1.1.
But only if your IP is publically seen on the internet (i.e., should be static ).
If its dynamic., then try to use dyndns.org.. or something similar.
Do port forwarding and enable DMz.
Best Regards & Happy New Year
