How this one compares
It was one of the good ones, for 16 days.

How HProxy checks 58.180.17.51:3128
58.180.17.51:3128 has been through 1,299 checks on HProxy's list, answering 1,008 of them. Few addresses in the database carry a record this long.
51 public sources published it
58.180.17.51 appears in 51 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 3128: Squid default
Port 3128 is the default for Squid, the most widely installed proxy software in the world. Most addresses published on 3128 are Squid servers that were meant to serve one office or one network and ended up reachable by everybody.
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 58.180.17.51:3128 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.
1,299 checks, 1,008 answered
That is 78% of the time, measured since July 8, 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. 58.180.17.51:3128 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 no other free proxies on Shinbiro, and 395 in South Korea. 58.180.17.51:3128 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
How many free proxies are on Shinbiro
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 4 addresses on AS4670, which is 0.00% of every address in the database and a small corner of the database. None of them are answering at the moment, though every one stays in the re-check rotation in case that changes.

Questions about 58.180.17.51:3128
Is 58.180.17.51:3128 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 24, 2026. We still re-test it periodically in case it returns.
Was 58.180.17.51 ever actually a proxy?
Yes. We ran 1,299 checks against it and it answered 1,008 of them, about 78% of the time, over 16 days on our list.
Where was 58.180.17.51 hosted?
South Korea, Shinbiro (AS4670). 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 Shinbiro?
None other than 58.180.17.51:3128 at the moment. AS4670 (Shinbiro) has no other free proxies live in our pool right now, though that changes as we re-verify.
Are there other free proxies in South Korea?
Yes, 395 free proxies are exiting from South Korea in our pool right now, answering in 1459ms 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).
