How this one compares
It worked sometimes, for 55 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 5,074 proxies answering right now, the middle of the pack answers 14.7% of the checks we send it.

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 188.187.3.75:1080
188.187.3.75:1080 has been through 1,307 checks on HProxy's list, answering 179 of them. Few addresses in the database carry a record this long.
44 public sources published it
188.187.3.75 appears in 44 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 1080: SOCKS
Port 1080 is the officially registered home of SOCKS, which forwards any kind of connection instead of only web traffic. An address offered on 1080 is being presented as a general purpose tunnel, not just a web proxy.
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 188.187.3.75:1080 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.
1,307 checks, 179 answered
That is 14% of the time, measured since June 11, 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. 188.187.3.75:1080 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 14, 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 SPB-AS, and 198 in Russia. 188.187.3.75:1080 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 SPB-AS
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 5 addresses on AS51570, 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 188.187.3.75:1080
Is 188.187.3.75:1080 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 August 5, 2026. We still re-test it periodically in case it returns.
Was 188.187.3.75 ever actually a proxy?
Yes. We ran 1,307 checks against it and it answered 179 of them, about 14% of the time, over 55 days on our list.
What is the hostname for 188.187.3.75?
Its reverse DNS record is 188x187x3x75.static-business.spb.ertelecom.ru. 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 188.187.3.75 hosted?
St Petersburg, St.-Petersburg, Russia, SPB-AS (AS51570). 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 SPB-AS?
None other than 188.187.3.75:1080 at the moment. AS51570 (SPB-AS) has no other free proxies live in our pool right now, though that changes as we re-verify.
Are there other free proxies in Russia?
Yes, 198 free proxies are exiting from Russia in our pool right now, answering in 2479ms 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).
