How HProxy checks 221.161.204.152:3164
HProxy has checked 221.161.204.152:3164 249 times and it answered 4 of those. Every one of those was a real connection attempt, never a lookup.
5 public sources published it
221.161.204.152 appears in 5 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 3164: 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 221.161.204.152:3164 and gives it up to 90 seconds to answer. Slow is not the same as dead, 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.
249 checks, 4 answered
That is 2% of the time, measured since July 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. 221.161.204.152:3164 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 24 hours. Its last check was on August 8, 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 50 other free proxies on Korea, and 309 in South Korea. 221.161.204.152:3164 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
What HProxy holds on Korea Telecom
Open proxies are not spread evenly across the internet. They cluster, because one misconfigured template, one cheap hosting reseller or one leaked image tends to produce hundreds of identical machines on the same network. HProxy tracks 2,632 addresses on AS4766, which is 0.45% of every address in the database and a meaningful pocket of the database. 50 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 221.161.204.152:3164
Is 221.161.204.152:3164 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 July 17, 2026. We still re-test it periodically in case it returns.
Was 221.161.204.152 ever actually a proxy?
Yes. We ran 249 checks against it and it answered 4 of them, about 2% of the time, over 1 day on our list.
Where was 221.161.204.152 hosted?
South Korea, Korea Telecom (AS4766). It is a residential or ISP address rather than a datacenter one.
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 Korea?
50 other free proxies are live on Korea (AS4766) in our pool right now, alongside 221.161.204.152:3164. 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 South Korea?
Yes, 309 free proxies are exiting from South Korea in our pool right now, answering in 2382ms at the median. If this address is not usable, that list is the place to look for a working one.
Upgrade to the paid network
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).
