Setup A (Address) Record: Point a Domain Name to an IP Address
"A Record" is a type of DNS record that allows you to point your domain name to an IP Address.
In this video we will see how you can setup an "A Address" with your domain control panel.
Although I have used Namecheap's control panel and Posterous's IP Address in this video but the core step remains same for all other domain providers/control panels like that of GoDaddy, eNom, Domainz, Dynadot, Name.com, Network Solutions, Tucows, Register.com etc.
