It seems strange that having two completely independent dns servers with different information gets the name ‘split dns’.

Reading the Wikipedia page seems to indicate more like one dns server hands out different data based on where the request is coming from.

But I guess it’s splitting hairs either way.

Run a local dns. Have an entry in the local dns that points to the internal ip.

I do this for home assistant using pihole.

When my phone is connected to my WiFi, it uses my local dns. When outside my home it uses public dns,

Works a charm.

You don’t need ‘split dns’ whatever that is. You just need your local DNS to forward to some public dns like google or whatever your provider uses.

Is there some kind of reverse Turing test?
