I'm hitting my search limit with a shared IP address
We track TinEye search usage based on your device's IP address. It’s quite common for Internet connections to be set up so that one IP is used by multiple devices or connections (known as dynamic IP). So it is possible that it’s not your personal searches that reached the limit, but searches by other people using the same IP address.
The simple way to get around this problem is to sign up for a free TinEye account. Then, whenever you are logged in to the site, only your personal searches count towards your limit.
