Search List

The search list can contain one static entry defined by the user the DNS Settings page and dynamic entries
received from DHCPv4 and DHCPv6 servers.
To view the domain names that have been configured on the device:
STEP 1
The following fields are displayed for each DNS server configured on the device.
• Domain Name—Name of domain that can be used on the device.
• Source—Source of the server's IP address (static or DHCPv4 or DHCPv6) for this domain.
• Interface—Interface of the server's IP address for this domain.
• Preference—This is the order in which the domains are used (from low to high). This effectively
determines the order in which unqualified names are completed during DNS queries.

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
STEP 2
• Static Only—Deletes the static hosts.
• Dynamic Only—Deletes the dynamic hosts.
