How HProxy checks 173.211.8.209:6321
173.211.8.209:6321 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 6321: 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 failure here was measured, not assumed
Each check opens an actual connection to 173.211.8.209:6321 and waits up to 4 seconds for the other end to complete a proxy handshake. Nothing about this record is inherited from the list that published the address. 1 times HProxy tried, and 1 times the connection did not complete inside that budget, which is why the answer on this page is a flat no rather than a maybe. The handshake is attempted across HTTP, HTTPS, SOCKS4 and SOCKS5, which is how we know it spoke HTTP.
1 checks, zero connections
Not one of those 1 attempts reached a working proxy. The address stays in the database with that result attached, because "we tried 1 times and it never answered" is a far more useful answer than silence for anyone who found 173.211.8.209 somewhere and wants to know what it is.
It is being re-tested continuously
173.211.8.209:6321 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.

What HProxy holds on Colocation America Corporation
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 1,187 addresses on AS21769, which is 0.20% of every address in the database and a meaningful pocket of the database. 2 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).
