My IP Detection Tool Drunk?

We've got this neat little web tool called 'What is My Country? - Find Your Current Country & IP Location' that's supposed to tell users where they are based on their IP. Pretty straightforward stuff, right? Well, lately, our IP detection seems to have hit the pub a little too hard. We're seeing some genuinely bizarre results – users in London apparently chilling in Antarctica, or their location jumping between three different countries within a minute. It's totally messing with the user experience and making the tool look... well, drunk. So, what on earth could be causing such wildly inconsistent IP detection and geolocation data? Are there common pitfalls with certain IP databases or the various geolocation APIs out there that might lead to this kind of erratic behavior? And more importantly, any specific debugging steps or best practices you'd recommend to get our IP detection sober and accurate again? Seriously need some expert insights to fix this before our users think we're running a prank site! Waiting for an expert reply.
