DNS Terminology

https://tools.ietf.org/html/rfc7719 #

The DNS is defined in literally dozens of different RFCs. The terminology used by implementers and developers of DNS protocols, and by operators of DNS systems, has sometimes changed in the decades since the DNS was first defined. This document gives current definitions for many of the terms used in the DNS in a single document.

I saw this RFC has just been published and decided to save it here for further reference since DNS was always a mine field for me.
