Does that even work? I thought all 127/8 was loopback

That whole /8 is reserved for loopback, but sometimes (usually?) only 127.0.0.1 is implemented as a loopback if you know that that’s true of your equipment, you could use the rest of that space for local addresses instead of 192.168/16, 172.16/12 and/or 10/8.

		Linux has a few sysctls that allow you to treat 127/8 as normal addresses. probably a Bad Idea to enable them though

		On my (fedora) system I can ping 127.anything and the host responds. I think in practice it is indeed implemented. I haven't used windows/macos in a very long time but I think the same applies. (Also in fedora by default systemd-resolved binds to 127.0.0.53)
