Hi, what is the point of buying a domain to access devices in LAN via Wireguard? (alien.top)

I have read many posts in this subreddit and so many recommend using a domain (buying it) and then registering DNS.

Maybe I misunderstood because I'm new, but in theory isn't it enough to use a DNS in lan like pihole, and then from the client browser using Wireguard simply write the domain defined on pihole? (Maybe even configuring nginx to have all the ports pointing to the correct services)

Am I wrong?

Lack of time or interest (or both) in: managing local DNS, using .home.arpa and running own CA.

It's tricky (especially running your own CA in a proper way), and not everyone wants to do it. Also, running it in a proper way it requires knowledge, and some people don't have it...

Actually, distribution of your root CA certificate is not that difficult.

NOTE: this addresses strictly OP's question about LAN-only access. External access or varying devices used to access is a completely different story.
