My father and I have the same IP address on my network. (I found this on cmyip.com) This makes it impossible for me to host servers (for instance minecraft or terraria) and I don't know the solution. Everyone I've asked so far says "Set a manual IP" but nothing I've found shows me how.
Anyone got any help? I kind of desperate after a year and a half of this...
