Administrative Options: DNS

DNS server address

The address of a DNS server that NetTracker can use to resolve host names. Usually, NetTracker can retrieve the address automatically. However, sometimes this information is impossible to retrieve on a Windows system and must be entered manually. (For more details, see "Manually Specifying the DNS Server Address".)

Maximum simultaneous DNS requests

The number of requests for host name resolution that can be pending at once. Because each pending request uses both memory and network resources, lowering this value can lower NetTracker memory use and network resource use when NetTracker is set to resolve host names.

The default is 2000. In general, this value should not be altered without consulting Sane Solutions technical support. (For details, see "Changing the Number of IP Addresses NetTracker Resolves at One Time".)

Reverse DNS timeout

The number of seconds that NetTracker will wait before stopping a DNS lookup. You can enter a number from 2 to 120. The default value is 3. The slower your connection, the larger your timeout setting should be. (For details, see "Specifying How Much Time to Allow for a Reverse DNS Lookup".)

Reverse DNS retries

The number of times that NetTracker will attempt to resolve a host name. You can enter a number from 0 to 100. The default is 4. (For details, see "Specifying How Many Times NetTracker Should Retry a DNS Lookup".)
