I've been having trouble with ipv4 port forwarding on my router, mainly that It doesn't excist. so i had to just do ipv6 by trial and eroor since i couldn't find a tutorial for that with my router. i came to the conclusion that it may not be neccesary. ive tried checking it by making a hostspot on another computer on my network. i on that netwerk tried localhost and it didn't work which was expected but i then tried typing in ipv6 adress of my host pc and it worked.
but I can't verify it outside of my network as I don't know that many people who play minecraft
so if someone with a ipv6 router could try to connect to it i'd be grateful.
please just message me as It's not always online
if you see any faults with my logic or are confused as to how or what i'm doing 1. you're not the only one. 2 i'd be happy to clearify.
