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 Ve rizon, it will also be config-
ured to use Ve rizo n’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.
