5.5.5.4 Internal DNS Table
The internal DNS table, similar to a DNS resolution, translates hostnames into IP
addresses. This table is used when hostname translation is required (e.g., ‘Tel to IP
Routing’ table). Two different IP addresses can be assigned to the same hostname. If the
hostname isn’t found in this table, the gateway communicates with an external DNS server.
Assigning two IP addresses to hostname can be used for alternative routing (using the ‘Tel
to IP Routing’ table).

To configure the internal DNS table, take these 7 steps:
1. Open the ‘Internal DNS Table’ screen (Protocol Management menu > Routing
Tables submenu > Internal DNS Table option); the ‘Internal DNS Table’ screen is
displayed.

2. In the ‘Domain Name’ field, enter the hostname to be translated. You can enter a
string up to 31 characters long.
3. In the ‘First IP Address’ field, enter the first IP address that the hostname is translated
to.
4. In the ‘Second IP Address’ field, enter the second IP address that the hostname is
translated to.
5. Repeat steps 2 to 4, for each Internal DNS Table entry.
6. Click the Submit button to save your changes.
7. To save the changes so they are available after a power fail, refer to Section 5.10.2 on
page 205.
