Then you open your registrar’s configuration, you figure out that you probably need to add some CNAME and A record entries. But what in the name of god are those two things.
This post is to help you get the gist of it in, lets say, 20 seconds!
CNAME: Always points to another domain name.
A Record: Always points to an IP Address.
Usually, you will setup stuff just the way its shown in the diagram so that tomorrow even if you feel a need to change your host ip address, just update your A Record mapping and you’re good to go.
