Domain Name

[viper0070]

I recently registered a domain name. Then I needed a DNS server to host my
record, my ISP does not offer one so I found a free one. It is
www.granitecanyon.com. I tried to sign up but then I have to put some kind
of code that is called "RR" or something. How do i have it point to an IP
adress, what do I have to put there? I would really apreciate if someone
would check out www.granitecanyon.com and see, thanks. Please email me at
viper0070 at yahoo.com
~Thank You
