Where this address sits
Right now our free pool holds 47 other free proxies on Korea Telecom, and 254 in South Korea. 183.101.185.89:20001 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 25838ms it is slower than the 2002ms median for South Korea proxies.
Korea Telecom is the 19th 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 4,755 addresses on AS4766, which is 0.51% of every address in the database and a meaningful pocket of the database. That makes it the 19th largest source of free proxies of every network we have ever seen. 48 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.

Continuous monitoring
How HProxy checks 183.101.185.89:20001
183.101.185.89:20001 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 20001: 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.
It has answered every single check
Each check opens a real connection to 183.101.185.89:20001 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. 183.101.185.89:20001 has completed that handshake on all 57 attempts so far, which is rare on a free public proxy and worth treating with some suspicion until the record is longer. The handshake is attempted across HTTP, HTTPS, SOCKS4 and SOCKS5, which is how we know it spoke HTTP.
57 checks, 57 answered
That is 100% of the time, measured since October 20, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
183.101.185.89:20001 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 183.101.185.89:20001?

Is it safe to use 183.101.185.89:20001?
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.

47 other free proxies are live on Korea Telecom (AS4766) in our pool right now, alongside 183.101.185.89:20001. 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.
183.101.185.89:20001 has answered 100% of our checks, which puts it well above most of what we track.

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).
