Where this address sits
Right now our free pool holds 2,226 other free proxies on Amazon, and 1,496 in Canada. 16.52.81.236:56192 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 339ms it answers faster than the 476ms median for Canada proxies (about 71% of it).
Amazon.com, Inc. is the 2nd largest source of free proxies we have ever measured.
Open proxies cluster rather than spreading evenly across the internet. Hosting providers and cloud platforms run enormous numbers of near-identical servers, so a handful of networks end up carrying a disproportionate share of every public proxy list, including ours. HProxy tracks 31,597 addresses on AS16509, which is 5.3% of every address in the database and a substantial share of everything HProxy tracks. That makes it the 2nd largest source of free proxies of every network we have ever seen. 2,227 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.

How HProxy checks 16.52.81.236:56192
16.52.81.236:56192 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 56192: Ephemeral port range
This is a throwaway port number, the kind a computer hands out for a few minutes and then takes back. Anything published on one tends to move or disappear when its host restarts, which is a large part of why public proxy lists rot so fast.
Every check is a real connection
HProxy does not read this address off somebody else's list and pass it on. Each check opens a real connection to 16.52.81.236:56192 and gives it up to 90 seconds to answer. Slow is not the same as unreachable, and plenty of working proxies take half a minute to reply. 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 HTTPS and SOCKS4 and SOCKS5.
2,690 checks, 348 answered
That is 13% of the time, measured since July 7, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
16.52.81.236:56192 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.

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).
