If you find the answer please let me know, sir.

Yes please.

net is /survival, org is /economy. They used to be separate servers and you used the two different urls to connect, but now you can connect to either one and switch between the two using commands.

Oh? How would you connect directly to the Org server without going through "survival" first...?

both domains direct you to the survival server, so you would just type /economy or /server economy to get to the economy server from there.

I guess they use BungeeCord or Lilypad then.
