As V1ct0ri0u5 said, it was probably an IP ban intended for someone else.

What happened is on October 18th, someone using your current IP address likely vandalized a wiki and was banned. IP addresses are not permanent, devices often cycle through new ones every so often, so think of it as a "reverse lottery". Your new IP address happened to match a banned IP address.
