Check If Host Exists Action
The Check If Host Exists action allows you to query a DNS server to determine if a host exists.
To determine if a host exists:
- Specify the name of the host that you want to check.
- Choose a DNS server to query:
- Default Server - selecting this option will query the server which is defined as the current machine's DNS server.
- Specific Server - specify the DNS server to query.
- Set the options:
- Fail if Host cannot be found- The action will fail if the host is not found. If not selected, the action will pass regardless (a warning will be raised if the host is not found).
- Timeout - Specify the timeout value at which point the query will be abandoned if the host has not been found.
