Proxy Checker
Paste one proxy or a whole list. Our checker sends a real connection through every proxy on your list to a public what-is-my-IP service and shows you what that site sees: exit IP, city, ISP, ASN and round-trip time. Then export the ones that work.
| # | Proxy | Status | Protocol | Latency | Exit IP | Location | ISP / ASN |

How the check works
Lines that start with a scheme (http://, https://, socks4://, socks5://) use that protocol, the rest go by the menu above, and Auto tries HTTP CONNECT before SOCKS5 and then SOCKS4. If the port is completely silent, the line fails right away and doesn't wait on every protocol. Latency includes everything in the round trip through the proxy, connecting, tunneling, TLS and one request to the lookup service, so a carrier network naturally reads higher than a datacenter.
What a good result looks like
Look for AT&T, T-Mobile or Verizon as the ISP on a mobile line and a city that fits the metro you bought; working lines on a US carrier say "Working · mobile". Check the list twice during a sticky session, and the exit IP ought to stay the same. If SOCKS5 passes and HTTP doesn't, switch your tool to the SOCKS5 port.
Deeper checks
IPFighter's free tools go well with this checker for testing fingerprint, bot detection and leaks on the same connection:
IP score & lookup ↗ Browser fingerprint ↗ Bot detection ↗ DNS leak test ↗ WebRTC leak test ↗
Your login details are used for the check, and we never log or store them. Up to 200 lines go in each run, four at a time, and one address can do up to 200 checks every ten minutes. Private and internal addresses are refused.
