The DNS SET-UP MENU contains options used to configure and maintain the DNS parameters for this device. The
DHCP server will supply the IP address of the primary and secondary Domain Name Servers when this router is
configured as a DHCP server. The DHCP server will not return an IP address if the DNS entries in this menu are set to
none.
1 - Primary DNS
The Primary DNS option defines the IP address of the primary network Domain Name Server (DNS).
Default: [none]
2 - Secondary DNS
The Secondary DNS option defines the IP address of the secondary network Domain Name Server (DNS).
Default: [none]
3 - Domain Name
The Domain Name option allows the specification of a domain name of up to 254 characters.
Default: [none]
Considerations:
When setting up a router using IP addressing that will have a DNS server on the local network as well as a connection to
an external DNS server (such as in Internet Service Provider), the local DNS server should be set as the Primary DNS and
the external DNS server as the Secondary DNS.
