Hoping someone can help ELI5 on this topic; I know a little about DNS but not exactly the process on pointing services to it.

I have a personal domain I have been using for a few years now, purchased from domain.com. My name servers are pointing to panelboxmanager.com, that hosts my website. I also have MX records pointing to google for Gmail.

What do I need to do to setup my Tailscale devices so that I can access them via 'mydevice.mydomainname.com'? Is it easy enough/worth it?

Thanks in advance!!
