How to check a proxy’s exit IP, country, city and ISP

The IP address you connect to (the proxy’s address) is not always the IP websites see. Many residential and rotating proxies forward your traffic to a different exit IP, sometimes in another city or country than the seller advertised. Before using a proxy for location-specific work — checking local search results, ad previews, or a store’s regional prices — confirm where it really exits.

Manual check

1. Switch Chrome to the proxy.
2. Open an “what is my IP” service such as https://api.ipify.org — it shows the exit IP.
3. Look the IP up in a geolocation database to get country, city, ISP and time zone.

That is fine for one proxy. For a list it is slow, and every switch changes the proxy for all your open tabs.

Checking every proxy at once

ProxyNest checks proxies without switching your browsing: each test request is routed through the proxy being tested, while your tabs keep their current connection. For each proxy you get:

• Speed — time for a small request through the proxy;
• Exit IP — what websites see;
• Country, city, ISP and time zone of that exit IP (from the free GeoJS and ipwho.is databases);
• or the reason it failed: unreachable, timeout, wrong password, or SOCKS5-with-password (unsupported by Chrome).

How accurate is IP geolocation?

Country is right for the vast majority of IPs. City can be off by tens of kilometres, especially for mobile and some residential ranges, and different databases disagree. Websites use their own databases, so treat the city as a good hint, not a guarantee. If a proxy matters for one specific site, check what that site shows.

Next step: is anything leaking?

Even with a working proxy, WebRTC can reveal your real address, and your browser’s time zone may not match the proxy. See how to fix WebRTC leaks and time zone mismatches.
