IT/Software/Server Config/ZoneEdit

This is the website that we use to manage our domains and DNS

Years ago I missed the chance to have one domain and everything be a subdomain.

Now I am managing 6 domains when I could have had only one. We may still consolidate in the future.

My understanding of DNS is weak at best.

Basics

A Names are records that are permanent and static and always at one address.

C names are subdomains that point to another part of the domain or to an entirely outside domain/location.

CAA records are records that tell an SSL provider that they can write a cert for that site. Confirms your ownership.

DYN records are psuedo records that can be updated with a dynamic DNS client. Useful when you have a server on a dynamic IP. At the MSG we have stuck with ddclient.
