How HProxy checks 8.209.253.237:50001
8.209.253.237:50001 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 50001: Ephemeral port range
This port sits in the ephemeral range, the block an operating system hands out temporarily for outgoing connections. A proxy advertised on one of these is usually a short-lived forward, often a home router mapping or a NAT translation, and it commonly stops working after a reboot or a lease change. That is a large part of why so many addresses in public lists never answer.
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 8.209.253.237:50001 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.
2,344 checks, 489 answered
That is 21% of the time, measured since June 23, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
8.209.253.237:50001 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 588 other free proxies on Alibaba, and 508 in Japan. 8.209.253.237:50001 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 4489ms it is slower than the 768ms median for Japan proxies.
What HProxy holds on Alibaba (US) Technology Co., Ltd.
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 8,981 addresses on AS45102, which is 1.5% of every address in the database and a substantial share of everything HProxy tracks. 2,437 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).
