How HProxy checks 91.239.211.83:8443
91.239.211.83:8443 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 8443: 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.
It has answered every single check
Each check opens an actual connection to 91.239.211.83:8443 and waits up to 4 seconds for the other end to complete a proxy handshake. 91.239.211.83:8443 has completed that handshake on all 3 attempts so far, which is rare on a free public proxy and worth treating with some suspicion until the record is longer. The handshake is attempted across HTTP, HTTPS, SOCKS4 and SOCKS5, which is how we know it spoke HTTP and HTTPS and SOCKS5.
3 checks, 3 answered
That is 100% of the time, measured since August 6, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
91.239.211.83:8443 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.

Where this address sits
Right now our free pool holds 8 other free proxies on Hostkey AS, and 350 in Germany. 91.239.211.83:8443 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 2389ms it is slower than the 2134ms median for Germany proxies.
What HProxy holds on HOSTKEY-AS
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 244 addresses on AS57043, which is 0.04% of every address in the database and a small corner of the database. 18 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).
