Host Mapping
Host name/IP address mappings are stored in the Host Mapping Table (DNS
cache).
This cache can contain the following type of entries:
•Static Entries—These are mapping pairs that were manually added to the
cache. There can be up to 64 static entries.
•Dynamic Entries—These are mapping pairs that were either added by the
system as a result of being used by the user, or and an entry for each IP
address configured on the device by DHCP. There can be 256 dynamic
entries.
Name resolution always begins by checking static entries, continues by checking
the dynamic entries, and ends by sending requests to the external DNS server.
Eight IP addresses are supported per DNS server per host name.
To add a host name and its IP address:
STEP 1 Click IP Configuration > Domain Name System > Host Mapping.
STEP 2 If required, select the Clear Table option to clear some or all of the entries in the
Host Mapping Table.
•Static Only—Deletes the static hosts.
•Dynamic Only—Deletes the dynamic hosts.
•All Dynamic & Static—Deletes the static and dynamic hosts.
The Host Mapping Table displays the following fields:
•Host Name—User-defined host name or fully-qualified name.
•IP Address—The host IP address.
•IP Version—IP version of the host IP address.
•Type—Is this a Dynamic or Static entry to the cache.
•Status— Displays the results of attempts to access the host
