6.3 DNS (Advanced Mode only)

DNS, or Domain Name System, is a naming system that translates between domain names (www.cradlepoint.com, for

example) and internet IP addresses (206.207.82.197). A DNS server acts as an internet phone book, translating between

names that make sense to people and the more complex numerical identifiers. The DNS page for the IBR600 has these

distinct functions:

 DNS Settings: By default your router is set to automatically acquire DNS servers through your internet provider

(Automatic). DNS Settings allows you to specify DNS servers of your choosing instead (Static).

 Dynamic DNS Configuration: Allows you to host a server (Web, FTP, etc.) using a domain name that you have

purchased (www.yourname.com) with your dynamically assigned IP address.

 Known Hosts Configuration: Allows you to map a name (printer, scanner, laptop, etc.) to an IP address of a

device on the network.

6.3.1 DNS Settings

You have the option to choose specific DNS

servers for your network instead of using the DNS

servers assigned by your internet provider. The

default DNS servers are usually adequate. You

may want to assign DNS servers if the default

DNS servers are performing poorly, if you want

WiFi clients to access DNS servers that you use for customized addressing, or if you have a local DNS server on your

network.

Automatic Config: Automatic or Static (default: Automatic). Switching to ―Static‖ enables you to set specific DNS servers

in the Primary DNS and Secondary DNS fields.

Primary DNS and Secondary DNS: If you choose to specify your DNS servers, then enter the IP addresses of the

servers you want as your primary and secondary DNS servers in these fields. For example, Google Public DNS servers

have the IP addresses 8.8.8.8 and 8.8.4.4 while 4.2.2.2 and 4.2.2.3 are servers from Level 3 Communications.
