Which wiki is this on?

It looks like it may indeed be a range block you're caught up in, or if you're in a public location (like a school or library), that IP was used by a vandal in the past.

If you get the message again, you should be able to see which admin made the block. Contact them. If it's made by a member of Staff (and has a block ID), use Special:Contact/general.
