A lot of services today authenticate DNS via TXT records and i find myself looking for web-services that checks those values for me. However, doing this will only give me the DNS record(s) for the DNS where the service is running, not actually my local DNS response.
Doing this via the Mac/OSX Terminal (command line) is trivially easy:
dig -t txt domain.com
Which will give you the TXT record for the specified domain. You can change the “txt” part to any other DNS parameters.
