following up on my previous post:

it turns out that, like anything else weird in infrastructure, it was DNS

I registered mydomain.com as my primary router’s domain, re-ran the experiment with a fresh 128 char subdomain, and I received zero scans on the new domain.

Now my question is, who’s making that one query that leaks my domain name? Is it Apache on startup?

One solution is to resolve all my subdomains on /etc/hosts so it never has to leave the box, but I’m curious what a more experienced net admin would suggest.

Not a net admin but I would enforce a LAN-only DNS server for all relevant clients and put the records there. And/or put such an infra behind a VPN like Tailscale so bots don't see it.
