Find DNS record programmatically:
Lets begin with MX Record a very simple example just for FUN !!

MX Record:
A mail exchanger record (MX record) specifies the mail server responsible for accepting email messages on behalf of a domain name. It is a resource record in the Domain Name System (DNS).

Occasionally on penetration testing/ethical hacking engagements we encounter misconfigured mail servers which creates an opportunity to either gather information on usernames or send emails impersonating internal users. Hackers love this scenario – we have encountered instances where threat actors find these vulnerable servers and just pour impersonation phishing attempts through, attempting to trick users into sending gift cards, bitcoin and wire transfers.
