Connecting to PiHole changes my computer's hostname?

0

I followed these instructions to create a VM in Google Cloud Platform that hosts PiHole (a DNS-based ad-blockign service) for me. To prevent the terrors of an open DNS provider, the PiHole is protected behind an OpenVPN server.

My router (Asus RT-AC68U) run an OpenVPN client which connects to the PiHole, and has its DNS servers set to 10.8.0.1 (the PiHole over the VPN) and blank.

When I'm at work, my computer's hostname is Alexs-Work-MacBook-Pro.local. But when I connect at home (behind this PiHoled router), my hostname changes to Alexs-Work-MBP.local.

If I replace the second blank DNS server with 1.1.1.1 (or some other provider), and restart my WiFi, my hostname goes back to Alexs-Work-MacBook-Pro.local.

What gives?

Are you talking about your computer's local hostname or the public address hostname? – Ecstasy – 2020-02-28T19:52:29.987

@Ecstasy Could you please explain the difference? I think I'm talking about my "local hostname", the one that comes up when I run the hostname command in bash – Alexander - Reinstate Monica – 2020-02-28T20:10:38.610
