Local DNS Table 19
Local DNS Table
The LAN Modem now includes a local DNS Table for configuring up to ten static
DNS entries, allowing the LAN Modem to resolve designated IP addresses locally.
The Local DNS Table can be used to suppress spurious calls caused by an
application on the LAN generating packets, which is in turn launching unwanted
calls to your service provider.
For example, to suppress spurious calls, do the following. If an application on the
LAN is generating packets to "my_net.com", you would enter "my_net.com" in
the Domain Name field, and then enter 192.168.1.29 in the IP address field. This
is an IP address that resides on the LAN Modem's default subnet, but by default is
not used by any attached workstations. Now, packets to "my_net.com" will be
routed to this unused IP address, and will no longer launch automatic calls.
Another potential application of the Local DNS Table is to assign a domain name
to a frequently visited IP address. In this case, you would enter the IP address in the
IP address field, and enter a domain name of your choice, such as "my_site.com"
in the Domain Name field. This will resolve the name "my_site.com" to the
associated IP address.
Access the DNS Configuration Table by clicking the Advanced button from within
the LAN Modem's main page. The DNS Configuration table opens, as shown in
Figure 10.
