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 MBR95 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 (DynDNS) Configuration:
Allows you to host a server (Web, FTP, Game Server, 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 (xbox, nas, toaster, 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.
