My Own DNS Server at Home – Part 1: IPv4

> I really should use the official .internal TLD (Top Level Domain) for my homelab network, but I decided against it. This introduces the risk of name resolution problems, should someone offer a public .jhw TLD in future. It’s a risk I am willing to accept in exchange for using a 3 letter TLD at home. Don’t be like me! Use .internal instead. With that out of the way, let’s continue.

Why not .lan? The key word is official?

My preference is to register a publicly resolvable domain and then just only use it internally. Then you can still get publicly trusted TLS certificates for it, in case you want them.

Doesn’t stop you from using your own private CA, either, but at least you have the option.
