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 211 other free proxies on Amazon, and 28,426 in United States. 3.92.47.79:49003 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 1534ms it answers faster than the 4298ms median for United States proxies (about 36% of it).
Amazon.com, Inc. is the 40th 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 1,424 addresses on AS14618, which is 0.20% of every address in the database and a meaningful pocket of the database. That makes it the 40th largest source of free proxies of every network we have ever seen. 212 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 3.92.47.79:49003
3.92.47.79:49003 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 49003: Registered port range
This port sits in the middle range, where any ordinary program can listen without special permission. The number itself carries no reserved meaning, which tells you somebody picked it on purpose instead of accepting a default.
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 3.92.47.79:49003 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 SOCKS5.
11 checks, 10 answered
That is 91% of the time, measured since August 30, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
3.92.47.79:49003 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.

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.

211 other free proxies are live on Amazon (AS14618) in our pool right now, alongside 3.92.47.79:49003. Networks that host one open proxy usually host several, which is why the whole AS is worth browsing rather than just this address.

This one is good, and it will still disappear.
3.92.47.79:49003 has answered 91% of our checks, which puts it well above most of what we track. It is still a public endpoint with nobody standing behind it: nobody agreed to serve you, no capacity is set aside for you, and there is no warning on the day it stops.

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).
