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
device 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.example.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
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.
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.
Dynamic DNS Configuration
The Dynamic DNS feature 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. Most broadband Internet Service Providers assign dynamic (changing) IP addresses. When you use a Dynamic DNS service provider, you can enter your host name
to connect to your server, no matter what your IP address is.
