Where this address sits
Right now our free pool holds 66 other free proxies on Amazon, and 349 in Australia. 16.51.53.116:56492 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 853ms it answers faster than the 1016ms median for Australia proxies (about 84% of it).
Amazon.com, Inc. is the 4th 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 57,381 addresses on AS16509, which is 6.0% of every address in the database and a substantial share of everything HProxy tracks. That makes it the 4th largest source of free proxies of every network we have ever seen. 67 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 16.51.53.116:56492
16.51.53.116:56492 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 56492: 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 16.51.53.116:56492 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.
1,318 checks, 42 answered
That is 3% of the time, measured since October 7, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
16.51.53.116:56492 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.

How fast is 16.51.53.116:56492?

Is it safe to use 16.51.53.116:56492?
Treat it the way you would any public proxy: it is operated by someone we have no relationship with, it is shared with strangers, and anything you send unencrypted over it can be read. Fine for a quick geo check or a scrape of public data, never for logins, payments or anything private.

66 other free proxies are live on Amazon (AS16509) in our pool right now, alongside 16.51.53.116:56492. Networks that host one open proxy usually host several, which is why the whole AS is worth browsing rather than just this address.

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).
