Interesting. So I'm guessing \\\\ is the delimiter being used there. I'm now wondering if that's a thing Minecraft servers normally know to handle.

Reading the protocol again for that field

https://minecraft.wiki/w/Java_Edition_protocol/Packets#Handshake

it dawned on me 🤦 of course, a typical server doesn't care what address it's referenced as. Only routers etc like mine care about that.

I'll get that enhanced in the next day or two.
