6.3 DNS

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/IBR650 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.
DNS Settings
6.3.1
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.
Force All DNS Requests To Router: Enabling this will redirect all DNS requests from LAN clients to the router's DNS
server. This will allow the router even more control over IP addresses even when clients have their own DNS servers
statically set.
