Is 174.138.165.210:21247 a proxy? Yes, it was.

It worked sometimes, for 0 days, and then it stopped.

It left the live pool here. Nothing is deleted: the address keeps this page and stays in the re-check rotation.
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.

How HProxy checks 174.138.165.210:21247
HProxy has checked 174.138.165.210:21247 173 times and it answered 12 of those. Every one of those was a real connection attempt, never a lookup.
2 public sources published it
174.138.165.210 appears in 2 of the public proxy sources HProxy tracks. Lists copy from each other constantly, so an address showing up in many of them says a lot about how widely it was republished and very little about whether it ever worked.
Port 21247: 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 174.138.165.210:21247 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, so a proxy is never missed because we guessed the wrong protocol.
173 checks, 12 answered
That is 7% of the time, measured since September 16, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
We are still watching for it to come back
Being archived does not stop the testing. 174.138.165.210:21247 answered before, so it is exactly the kind of address that can return, and the sweep works through the whole database and reaches every address roughly once every 12 hours. Its last check was on September 19, 2026, so the next one is due within a day of that. The moment it answers again it is promoted straight back into the live free proxy list, automatically, with no manual step.

Where this address sits
Right now our free pool holds 221 other free proxies on Secured Servers, and 26,955 in United States. 174.138.165.210:21247 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
SECURED SERVERS LLC is the 3rd 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 48,398 addresses on AS20454, which is 6.1% of every address in the database and a substantial share of everything HProxy tracks. That makes it the 3rd largest source of free proxies of every network we have ever seen. 221 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.

Questions about 174.138.165.210:21247
Is 174.138.165.210:21247 a working proxy?
No, not any more. It was a working public proxy in HProxy's free pool and has since gone dark, last answering on September 16, 2026. We still re-test it periodically in case it returns.
Was 174.138.165.210 ever actually a proxy?
Yes. We ran 173 checks against it and it answered 12 of them, about 7% of the time, over under a day on our list.
What is the hostname for 174.138.165.210?
174.138.165.210 publishes no reverse DNS record. That is not unusual and it is not suspicious on its own, but it does mean the address volunteers nothing about who runs it, so the network and the check history below are all there is to go on.
Where was 174.138.165.210 hosted?
Phoenix, Arizona, United States, SECURED SERVERS LLC (AS20454). It is a datacenter address, not a home connection.
Why keep a page for an address that no longer works?
Because "was this address ever a proxy, and when" is a real question. If you are looking at this IP in a firewall log or an abuse report, the dates and the check counts here are the answer. HProxy's public proxy IP list keeps every address it has ever tracked and carries on re-testing them, so deleting this record would throw all of that away.
How many free proxies are on Secured Servers?
221 other free proxies are live on Secured Servers (AS20454) in our pool right now, alongside 174.138.165.210:21247. Networks that host one open proxy usually host several, which is why the whole AS is worth browsing rather than just this address.
Are there other free proxies in United States?
Yes, 26,955 free proxies are exiting from United States in our pool right now, answering in 3406ms at the median. If this address is not usable, that list is the place to look for a working one.

Need pools that stay clean?
Free IPs are shared and rotate out fast, so success rates swing. The paid network gives you dedicated-clean pools that hold up under load.
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).
