Adig

Overview

Advanced dig script that queries default name server on your workstation, google, the liquidweb name server and name servers returned by dig (/registrar).

Good for finding differences being reported by different name servers.

Searching for main domain will return all record types (A,MX,TXT,NS,CNAME etc).

Searching for subdomain will generally only return CNAME and A records.

Color codes records for easier viewing.

This should not be installed on customer servers
