I have to work with a lot of accounts on the same sites for my new job, and my real location isn’t supposed to be tied to them. I’ve been buying private proxies and using a different IP for each account, and every IP checker shows exactly the address I expect. The problem is that some sites still seem to know the registrations are coming from the same place. What else can they see besides the IP, and why does changing the proxy not solve it?
Honestly, after a few failed signups I’d probably start wondering whether the site had developed a personal grudge against me. Everything looks different on your side, yet somehow it keeps recognizing the same pattern over and over. That’s when it makes sense to check what the browser is exposing beyond the address you see on an IP checker. A privacy checker can show whether separate profiles still look too similar from the site’s side.
There’s also a quieter part of the connection that people rarely think about until something goes wrong. Everything can look clean on an IP check while DNS requests are still going through your regular network in the background, and that can point back to the same place. You can read about what a DNS leak is here: https://gologin.com/blog/what-is-a-dns-leak/ . An antidetect browser is worth using for privacy-sensitive work too, because it keeps separate browser profiles from sharing the same session data and browser identity. That gives you a much cleaner separation than relying on proxies alone.
