DNS: Using Names Instead of IP addresses
A domain name is a name of a server or device on the Internet which is associated, generally, with an IP address. In a way, a domain name is like the street address of your house with the phone number being like the IP address. You can contact the house either by going to the address (name) or by calling the phone number (IP address).
Domain Name Service (DNS) is a network service which translates, or redirects, the IP address, allowing someone to contact that address via the name. A DNS server is registered to handle all addresses of a particular domain (much like the post office for a particular town or city is known to the post offices of all other towns and cities and is authorized to give the addresses of locations in its own loca- tion).
Configuring DNS
The Raven has an internal DNS resolver with which it can query DNS servers in order to translate names into IP addresss which it can then use internally. Gener- ally, when your Raven receives its IP address from Verizon, it will also be config- ured to use Verizon’s DNS servers to use for resolving (or translating) names to IP addresses. In that case, the only one which is not overwritten is the alternate DNS.
You can use AT commands (page 53), Wireless ACE (page 10), and ACE Net (page 11) using a template built from Wireless ACE to configure DNS in your Raven.

*DNS1 and *DNS2 - Set these to your primary and secondary DNS servers. These maybe be overwritten by Verizon when your Raven gets its IP address.
