Secure Mobile Access 12.4 Administration Guide

Using DNS Lookup

You can use AMC’s Lookup tool to determine how DNS is resolving an IP address or a host name. This tool is useful for troubleshooting various DNS problems (for example, it can determine whether your DNS server is running).

Use a fully qualified domain name or an IP address to specify a host in the Lookup tool. However, you can type a non-qualified host name as long as you have defined one or more default search domains on the Configure Name Resolution page (available from the Network Settings page in AMC). For details on name resolution, see Configuring Name Resolution.

To determine how DNS is resolving an IP address or host name

  1. In the AMC, navigate to Monitoring > Troubleshooting.

  2. Click the Lookup tab.

  3. In the Address field, type the IP address or host name of the machine against which you want to issue the command.

  4. Click Go.
