Dns - Cradlepoint ARC CBA850 Manual

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 CBA850 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 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, 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.
