Meet The DNS records

What I met the dns config as the web developer.

Firstly,

I didn’t know types of dns records such as NS,A Record, CName,MX,SPF,DKIM,TXT & etc…

I won’t tell what is dns records , if you want to know go on type “what is dns records” into google search.

But, I will explain how can I use these records as web developer for our websites(domain & subdomains) and email addresses.
