I don't think anyone else is using my IP either, the only ones I know using it on Wikia is me and my brother. IP's are dynamic and are almost always shared by many other customers on your ISP, because the old style IPv4 addresses are all used up, so ISP's purchase a block of IP addresses for their network: they then configured their network so that customers are randomly routed through different clusters, which many other customers may be getting routed through, so all those customers get a specific IP to that cluster.

It is very likely (99% chance) that someone else had that IP previously and vandalised the wiki, or the wiki was experiencing a large amount of vandalism from a range of IP's on your ISP network that all had similar IP addresses. IP blocks like this supercede account blocks by default, hence why you can't edit because your IP matches that of a range block.

As RansomTime said, some admins misuse range blocks and block massive IP ranges, which essentially blocks many customers (and sometimes a whole ISP) from using a specific wiki. You can contact a sysop on the wiki and ask them to rescind the large range block as it's quite likely that it is no longer valid, or the sysop who applied the range block had no idea what he was using to block IP's. IP's should never be blocked longer than a month anyway.
