[FIXED] WHAT is "IN" in DNS records?

Issue

What is the proper meaning of the "IN" word in DNS records? DNS records are an important part of DNS zones. So I want to know that there is an "IN" word included in every record. what is the meaning?

It would help clarify what such a piece of information in DNS is?

Thank you for making all the efforts.

Solution

A simple INternet search would have brought you to Wikipedia, where the following is stated on DNS Record Classes:

The CLASS of a record is set to IN (for Internet) for common DNS records involving Internet hostnames, servers, or IP addresses. In addition, the classes Chaos (CH) and Hesiod (HS) exist.[34] Each class is an independent name space with potentially different delegations of DNS zones.
