Mapping DNS Hosts

Frequently-queried names, acquired from DNS servers in the past, are saved to a local DNS cache (up to 64 entries). In addition, you can enter DNS host names and their IP address. Name resolution always commences with these static entries, continues with the local DNS cache, and ends with requests to the external DNS server.

The Host Mapping Page enables configure static mappings between a DNS host name and an IP address.

Several IP addresses are supported per DNS per host name.

To add a domain name and its IP address:

Click IP Addressing > Domain Name System > Host Mapping. The Host Mapping Page opens.
