Where is your domain hosted? If it is at GoDaddy, here is how to do make the appropriate changes for your situation:
Log into your account
click on Domain Manager
Click on your domain (your-domain.com)
If you want to change your nameservers, click on "Set Nameservers"
Choose "I have specific nameservers for my domains"
replace the name servers with at least 2 different name servers
I chose to keep my domain managed at GoDaddy, because my email is hosted elsewhere
if you want to do this, I.E. you host your email with Google Apps
Go to Total DNS
Click on Total DNS Control
To point dns at your website, put in the apropriate IP address for the A (Host) record
@ 22.214.171.124 (now @ always points to the ip address for your webserver)
You have to log into your Cpannel to find this information under Account Details Overview:
"You can also point your domain ("A" DNS record) to IP 126.96.36.199"
For Google Apps, you will want to point the mail server CNAME host names to Google's servers:
MX Mail Exchange servers:
Priority Mail Server
