When you land on my-ip.club, the first problem is figuring out what the site is even for. The homepage content appears as garbled binary data, and there is no about page, no contact information, and no social media presence to give you any context. A legitimate service that has been around for 11 years should at minimum tell you who runs it and how to reach them.
On the technical side, the site uses modern encryption with a valid SSL certificate and loads quickly through Cloudflare. The domain has been registered since 2015 and has a clean history on blacklists and Google Web Risk. Those signals suggest the site isn't actively malicious, but they don't tell you whether you can trust the people behind it.
If you are considering using my-ip.club for any purpose that involves sharing data or relying on its functionality, the lack of transparency is a serious concern. Most websites in 2023 have at least a basic contact form or a privacy policy. The fact that this one has neither is a strong reason to proceed with caution, so you should avoid sharing any personal information until the site operator makes themselves known.
