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 218.78.128.193:12366
218.78.128.193:12366 has been through 1,657 checks on HProxy's list, answering 1,390 of them. Few addresses in the database carry a record this long.
48 public sources published it
218.78.128.193 appears in 48 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 12366: 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 218.78.128.193:12366 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.
1,657 checks, 1,390 answered
That is 84% 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. 218.78.128.193:12366 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 5, 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 allWhere this address sits
Right now our free pool holds no other free proxies on China Telecom (Group), and 2,720 in China. 218.78.128.193:12366 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
China Telecom (Group) is the 93rd 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 542 addresses on AS4812, which is 0.07% of every address in the database and a small corner of the database. That makes it the 93rd largest source of free proxies of every network we have ever seen. None of them are answering at the moment, though every one stays in the re-check rotation in case that changes.

Questions about 218.78.128.193:12366
Is 218.78.128.193:12366 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 28, 2026. We still re-test it periodically in case it returns.
Was 218.78.128.193 ever actually a proxy?
Yes. We ran 1,657 checks against it and it answered 1,390 of them, about 84% of the time, over 20 days on our list.
What is the hostname for 218.78.128.193?
218.78.128.193 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 218.78.128.193 hosted?
Shanghai, Shanghai, China, China Telecom (Group) (AS4812). 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 China Telecom (Group)?
None other than 218.78.128.193:12366 at the moment. AS4812 (China Telecom (Group)) 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, 2,720 free proxies are exiting from China in our pool right now, answering in 2681ms 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).
