How this one compares
It worked sometimes, for 3 days, and then it stopped.
Every free proxy list quotes an uptime figure. Almost none of them tell you what a normal one looks like, so here is ours: across the 3,797 proxies answering right now, the middle of the pack answers 15.6% of the checks we send it.

Most recent re-test
HProxy has opened 350 real connections to this endpoint in total. The sweep reaches every address in the database roughly once every 24 hours.
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 220.243.154.45:11143
HProxy has checked 220.243.154.45:11143 350 times and it answered 6 of those. Every one of those was a real connection attempt, never a lookup.
4 public sources published it
220.243.154.45 appears in 4 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 11143: 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 220.243.154.45:11143 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.
350 checks, 6 answered
That is 2% of the time, measured since June 22, 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. 220.243.154.45:11143 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 9, 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.

Live free proxies right now
View all →Where this address sits
Right now our free pool holds no other free proxies on IDC, China Telecommunications Corporation, and 680 in China. 220.243.154.45:11143 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 IDC, China Telecommunications Corporation
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 100 addresses on AS23724, which is 0.02% 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 220.243.154.45:11143
Is 220.243.154.45:11143 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 June 25, 2026. We still re-test it periodically in case it returns.
Was 220.243.154.45 ever actually a proxy?
Yes. We ran 350 checks against it and it answered 6 of them, about 2% of the time, over 3 days on our list.
Where was 220.243.154.45 hosted?
China, IDC, China Telecommunications Corporation (AS23724). 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 IDC, China Telecommunications Corporation?
None other than 220.243.154.45:11143 at the moment. AS23724 (IDC, China Telecommunications Corporation) has no other free proxies live in our pool right now, though that changes as we re-verify.
Are there other free proxies in China?
Yes, 680 free proxies are exiting from China in our pool right now, answering in 2782ms 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).
