I am trying to see if its possible to run nslookup -q=TXT domain 8.8.8.8 so i can compare the results of the output to an existing lookup csv file.

Hi urana,

The default shipped command dnslookup does not provide this functionality. If you need a fully featured command like linux dig you would need to created a custom search command yourself. It could be as easy as creating a wrapper for dig and output thew results to Splunk 😉 See the docs for an example to write a custom search command https://docs.splunk.com/Documentation/Splunk/latest/Search/Customsearchcommandshape

Hope this helps ...

cheers, MuS

While it may not be possible to do TXT queries out of the box, an app has now been created for this here

This app adds a custom dnsquery command which utilizes dnspython package under the hood and allows you to do DNS queries on hostnames - tested to work for CNAME, MX, TXT, A, PTR records.
