Technically there's no real problem here.
It responds to and serves content to unauthenticated requests. That’s sorta table stakes if you’re creating an authenticated web service and providing guides to set it up with a reverse proxy.
I’m slowly moving in the direction and have learned a lot, but in my home network, all my devices get a bunch of IPs and services seem to choose at random the IP to listen on. My ISP changes my prefix at random. Devices don’t register in DNS. So even if I use the ULA it’s a lot of fucking typing.
I also had this thing for a while where the MAC of a bhyve VM would change at boot so even the ULA changed. That fucked me for a while.
Opnsense lets me create aliases allowing me to create firewall rules, so at least that works now… kinda. But i haven’t figured out privacy extensions.
So yes, you’re right, 32 digits is a lot to keep in mind.
