i just got a bit of curiosity what'd happen if 2 fediverse servers tried to communicate, but communication was only possible in one direction (eg, a server running on a lan network and a public www server try to communicate)
Also yes i've got a fake domain for my LAN pleroma instance (you can make fake domains for LAN use either via hosts.txt or via selfhosting a dns server)
cause i have a pleroma server on a vm, but i don't wanna risk causing any problems
