• Split DNS: Enable or disable the redirecting of specified domains to alternate DNS servers.
• 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.
Mode: 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.
Split DNS
Split DNS allows you create two zones for the same
domain, one to be used by the internal network, the
other used by the external network. Split DNS directs
internal hosts to an internal domain name server for
name resolution and external hosts are directed to an
external domain name server for name resolution.
Primary Split DNS and Secondary Split 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 Secondary
DNS is optional.
Domain: Click Add to add desired domain for Split DNS.
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.
• Enable Dynamic DNS: Enable this option only if you have purchased your own domain name and registered
with a Dynamic DNS service provider.
• Server Type. Select a dynamic DNS service provider from the dropdown list:
