How HProxy checks 43.207.141.180:3509
43.207.141.180:3509 is in the live pool right now, and it stays there only for as long as it keeps answering. Here is exactly what HProxy does to it, and how often.
Port 3509: Registered port range
This port sits in the registered range, which any user-level program may listen on without special rights. It carries no reserved meaning of its own, so the number tells you the proxy was configured deliberately on a chosen port rather than on a system default.
Every check is a real connection
HProxy does not read this address off somebody else's list and pass it on. Each check opens an actual connection to 43.207.141.180:3509 and waits up to 4 seconds for the other end to complete a proxy handshake. Anything that does not answer in that budget counts as a failure and is recorded as one, which is why the percentage on this page moves rather than sitting at a marketing number. The handshake is attempted across HTTP, HTTPS, SOCKS4 and SOCKS5, which is how we know it spoke HTTP.
1,417 checks, 153 answered
That is 11% of the time, measured since July 10, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
43.207.141.180:3509 is in the live rotation, so it is re-tested continuously rather than on a daily cycle. If it stops answering it is marked down immediately, and if it stays down for 3 days it moves into the public proxy database with its full record intact. Nothing is deleted at any point.

Right now our free pool holds 5,621 other free proxies on Amazon, and 576 in Japan. 43.207.141.180:3509 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
What HProxy holds on Amazon.com, Inc.
Open proxies are not spread evenly across the internet. They cluster, because one misconfigured template, one cheap hosting reseller or one leaked image tends to produce hundreds of identical machines on the same network. HProxy tracks 7,020 addresses on AS16509, which is 1.2% of every address in the database and a substantial share of everything HProxy tracks. 16,118 of them are answering right now, so if this particular address is not usable, the network is a reasonable place to look for one that is.

About this list & IP removal
Every proxy here is aggregated from publicly available sources. We do not scan or collect these IP addresses ourselves: we verify entries that are already public (live status, latency, uptime) and store nothing else about the devices behind them. The list is provided as-is, with no warranty, for lawful use only, on the basis of our legitimate interest in a free, transparent proxy directory (Art. 6 (1) (f) GDPR). Never route passwords or sensitive data through a public proxy. If an IP address is yours and you'd like it removed, email legal@hproxy.com and we'll take it down (Art. 21 GDPR).
