ip.bi is a simple IP geolocation service that lets you look up your own or any IP address's approximate location, ISP, and more. At first glance, it seems like a typical free online tool — it has been running for six years, has a privacy policy and terms of service, and isn't tied to any known scams or blacklists. That's more than many similar sites bother with.
But there's a glaring problem: the site doesn't use HTTPS. That means when you visit ip.bi, a technically savvier person on the same Wi-Fi network (say, at a coffee shop) could see the IP address you're looking up and the website's response. For a tool that only shows public data, the privacy risk is limited to anyone being able to eavesdrop on your session. Legitimate competing services nearly all offer HTTPS by default, so there's no good reason for this gap.
If you just need a quick IP lookup and aren't concerned about someone seeing your traffic, ip.bi will give you the answer. But if you'd rather keep that query private, stick to a site that encrypts with HTTPS. There's no evidence that ip.bi is a scam or will harm your device — it's just a tool that hasn't been updated to a basic security standard that most web users now expect.
