What normal looks like

Every number above is measured against these two.

A percentage on a proxy list means nothing without the shape of the thing it came from. These are the two distributions the rest of this page compares against, drawn from HProxy's own checks rather than from anybody's marketing page.

Where this address sits

Right now our free pool holds 69 other free proxies on Amazon, and 279 in Israel. 51.16.4.39:9050 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 651ms it answers faster than the 807ms median for Israel proxies (about 81% of it).

Amazon.com, Inc. is the 5th 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 56,797 addresses on AS16509, which is 5.9% of every address in the database and a substantial share of everything HProxy tracks. That makes it the 5th largest source of free proxies of every network we have ever seen. 70 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 51.16.4.39:9050

51.16.4.39:9050 is in the live pool right now, and it stays there only for as long as it keeps answering.

  1. Port 9050: Tor SOCKS default

    Port 9050 is the Tor client's default SOCKS port. Something answering here is offering a way into the Tor network rather than an ordinary proxy hop.

  2. 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 51.16.4.39:9050 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.

  3. 2,315 checks, 245 answered

    That is 11% of the time, measured since July 23, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.

  4. It is being re-tested continuously

    51.16.4.39:9050 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 51.16.4.39:9050?

Is it safe to use 51.16.4.39:9050?

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.

How many free proxies are on Amazon?

69 other free proxies are live on Amazon (AS16509) in our pool right now, alongside 51.16.4.39:9050. 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).
