CRADLEPOINT MBR1400 | USER MANUAL – Firmware version 5.0

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 MBR1400 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. The DNS server settings will be pre-

populated with public DNS server IP addresses. You can override the IP address with any other DNS server IP address of

your choice. 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.
