DNS/WINS Settings

Use the DNS/WINS Settings section to specify the DNS server(s) and WINS server(s) that InterMapper uses. InterMapper uses your current DNS servers as its default.

InterMapper can use one or more Domain Name Service servers (DNS) to convert DNS names to addresses and back. InterMapper checks the listed DNS server(s) at regular intervals to make sure that the DNS name and IP address for a device match.

When you start InterMapper on a MacOS X or Windows machine, the DNS servers specified by the current network configuration are used. On Unix machines, you must enter one or more DNS server addresses manually.

The DNS addresses are optional: if the preference is empty, InterMapper does not attempt to make DNS <-> IP address conversions.

For example, when InterMapper polls a device that has a name assigned, it looks up the corresponding IP address in the DNS. If the resulting address has changed since the device was added to a map, InterMapper logs an error message.

Setting DNS Monitor Preferences

Set DNS Monitor preferences as follows:

• Comma-separated list of Domain Name Server addresses - Enter a list of Domain Name Server addresses, separated by commas.
• Search Domain - Enter a name to append to a partial domain name to make a fully-qualified domain name.
• Minimum interval between DNS checks - Set this value to the amount of time to wait between successive queries for a host. Use a larger value to reduce the number of times the DNS is checked.

Setting WINS Preferences

You can specify one or more WINS servers that InterMapper will use for WINS lookups. InterMapper can also fall back to broadcast lookups for WINS/NetBIOS name lookups. Unless instructed by your network administrator, you should usually leave the WINS Scope blank.

• Use WINS name resolution - Check this box to allow InterMapper to use the specified WINS servers to look up device names and addresses.
• Comma-separated list of WINS server addresses - Enter a list of addresses, separated by commas.
• Use broadcast if lookup fails - Check this box to allow InterMapper to use broadcast lookups for WINS/NetBIOS lookups if the WINS lookup fails.
• WINS Scope - Enter a WINS Scope. This should only be necessary if instructed by your network administrator.
