DNS

Domain Name System - Allows us to resolve human readable names to IP Addresses.

A-Records

A-Record stands for Address Record.

This records every IP address which is linked to a domain name.

AAAA-Records

AAAA-Record is the same as an A-Record but it is for IPv6 addresses.

C-Name

C-Names link two domain names together.

Forexample, if you link domain1.com to domain2.com, domain1.com will show an exac copy of domain2.com without redirecting
