I read “selfghosting” at first and thought this post was made in r/recruitinghell … Yeah… Well…

Glad it worked out so well for you though!

Oh god. I fell in love with you after reading this. :-)

That made smile. Glad you found help here and solved your issue!

So… You are going to set up a small DNS-Server next too? ;-)
No really, I can recommend PiHole for DNS-AdBlock and it allows to set DNS entries too. That’s why I use for my 2 Raspberries and the few VMs + network equipment.
