You can create a local DNS table to provide a list of IP addresses for a specific host name when
the remote DNS server fails to resolve the host name. If the local DNS table contains the host
name for the attempted connection, it provides the list of IP addresses.
You create the DNS table from the terminal server by entering the hostnames and their IP
addresses. A table can contain up to eight entries, with a maximum of 35 IP addresses for each
entry. If you specify automatic updating, you only have to enter the first IP address of each
host. Any others are added automatically.
Automatic updating replaces the existing address list for a host each time the remote DNS
server succeeds in resolving a connection to a host that is in the table. You specify how many
of the addresses returned by the remote server can be included in the new list.
On the MultiVoice Gateway, the table provides additional information for each table entry. The
information is in the following two fields, which are updated when the system matches the
table entry with a hostname that was not found by the remote server:
• # Reads—the number of reads since entry was created. This field is updated each time a
local name query match is found in the local DNS table.
• Time of Last Read
You can check the list of host names and IP addresses in the table by entering the
terminal-server command Show Dnstab. Figure 8-5 shows an example of a DNS table on a
MultiVoice Gateway. Other terminal-server commands show individual entries, with a list of
IP addresses for the entry.
