How is local network hostname and FQDN resolution handled?

Tailscale support:
The Magic DNS document describes hostname generation. In short, names will be of the form hostname.yourdomain.com.beta.tailscale.net and yourdomain.com.beta.tailscale.net is added to the resolver search path.

Hi,

I’m looking for a solution to name my VPN hosts with the use of my FQDN:
pc1.myrdomain.fqdn
pc2. … …
pc3. … …

It seems related, so I post my request here.
I’ve a fixed public IP on my ISP’s router and a FQDN @ easyhost.be.
My hosts are on different locations over Belgium and are already part of my Wireguard VPN with central server behind my own ISP router with my personal desktop.

Do you provide a solution to this with Magic DNS ?
Or will I still have to enter beta.tailscale.net after each name if I use your services?
