@Cutebot Ugh you nubs seem confused. An IP is an adress linked to your wifi router, and more specifically your computer. An IP ban will ban your account, and also ban the address that your router/computer has, so you cannot join with another account without a proxy. A proxy is a thing that will change your ip and make it appear to be another IP. Now is everyone good??? :D

(Sorry for helping if this thread was considered dead)

For the avoidance of misinformation in going to correct this.
An IP is connected to your router or more specifically your modem. It is not connected to your computer, if you take a computer and move it to a different Internet connection it will bypass the ban.
Nor does it auto ban an account if it's IP banned.

A proxy can conceal your IP but it isn't really suited for Minecraft either.
