How this one compares
8 attempts. Not one connection.
Being published on a proxy list is a claim that an address works. It is not a test, and nobody in that chain is obliged to have tried it. We tried 8 times, which is why the answer on this page is a flat no rather than a maybe.

Moved to the permanent record
It left the live pool here. Nothing is deleted: the address keeps this page and stays in the re-check rotation.

Most recent re-test
HProxy has opened 8 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 121.37.210.53:59345
HProxy has opened a connection to 121.37.210.53:59345 8 times and it has never once answered. That is a measurement, not an assumption, and it is the difference between this record and the lists that republished the address without testing it.
10 public sources published it
121.37.210.53 appears in 10 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 59345: Ephemeral port range
This is a throwaway port number, the kind a computer hands out for a few minutes and then takes back. Anything published on one tends to move or disappear when its host restarts, which is a large part of why public proxy lists rot so fast.
Every failure here was measured, not assumed
Each check opens a real connection to 121.37.210.53:59345 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. Nothing about this record is inherited from the list that published the address. 8 times HProxy tried, and 8 times the connection did not complete inside that budget, which is why the answer on this page is a flat no rather than a maybe. The handshake is attempted across HTTP, HTTPS, SOCKS4 and SOCKS5, so a proxy is never missed because we guessed the wrong protocol.
8 checks, zero connections
Not one of those 8 attempts reached a working proxy. The address stays in the database with that result attached, because "we tried 8 times and it never answered" is a far more useful answer than silence for anyone who found 121.37.210.53 somewhere and wants to know what it is.
It is still re-tested every 24 hours
121.37.210.53:59345 has never answered, and it is still in the rotation anyway. The sweep reaches every address in the database roughly once every 24 hours regardless of its history, because an address that was dark for months can be brought back online by whoever controls it without telling anybody. Its last check was on August 10, 2026, so the next one is due within a day of that. If that ever happens here, this page changes on its own.

Live free proxies right now
View all →Where this address sits
Right now our free pool holds 8 other free proxies on Huawei, and 643 in China. 121.37.210.53:59345 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
Huawei Cloud Service data center is the 156th 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 238 addresses on AS55990, which is 0.04% of every address in the database and a small corner of the database. That makes it the 156th largest source of free proxies of every network we have ever seen. 8 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 121.37.210.53:59345
Is 121.37.210.53:59345 a working proxy?
Not for us. 121.37.210.53:59345 was published as a public proxy by our sources, and across 8 checks since August 5, 2026 it has never answered.
Was 121.37.210.53 ever actually a proxy?
Not while we have been watching it, which is the honest limit of what we can say. Our record opens on August 5, 2026, and across 8 checks since then it has never answered us. 10 separate lists published it as a working proxy, so it may well have answered somebody before we first tested it. We report what we measured, not what we assume.
What is the hostname for 121.37.210.53?
Its reverse DNS record is ecs-121-37-210-53.compute.hwclouds-dns.com. That is what the address itself publishes about who operates it, which is often more telling than the network name: hosting providers name their machines by region and instance type, and a residential line usually carries its ISP's own pattern.
Where was 121.37.210.53 hosted?
Guangzhou, Guangdong, China, Huawei Cloud Service data center (AS55990). 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 Huawei?
8 other free proxies are live on Huawei (AS55990) in our pool right now, alongside 121.37.210.53:59345. 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 China?
Yes, 643 free proxies are exiting from China in our pool right now, answering in 3049ms 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).
