How this one compares

It worked sometimes, for 1 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 3,836 proxies answering right now, the middle of the pack answers 15.7% of the checks we send it.

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.

Continuous monitoring

How HProxy checks 91.186.217.170:3128

HProxy has checked 91.186.217.170:3128 294 times and it answered 26 of those. Every one of those was a real connection attempt, never a lookup.

  1. 10 public sources published it

    91.186.217.170 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.

  2. Port 3128: Squid default

    Port 3128 is the default for Squid, the most widely installed proxy software in the world. Most addresses published on 3128 are Squid servers that were meant to serve one office or one network and ended up reachable by everybody.

  3. 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 91.186.217.170:3128 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.

  4. 294 checks, 26 answered

    That is 9% of the time, measured since June 18, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.

  5. We are still watching for it to come back

    Being archived does not stop the testing. 91.186.217.170:3128 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 10, 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.

Where this address sits

Right now our free pool holds 1 other free proxy on Netcraftersou, and 200 in Sweden. 91.186.217.170:3128 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 NetCraftersOU

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 63 addresses on AS203273, which is 0.01% of every address in the database and a small corner of the database. 1 of them is 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 91.186.217.170:3128

Is 91.186.217.170:3128 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 19, 2026. We still re-test it periodically in case it returns.

Was 91.186.217.170 ever actually a proxy?

Yes. We ran 294 checks against it and it answered 26 of them, about 9% of the time, over 1 day on our list.

Where was 91.186.217.170 hosted?

Stockholm, Stockholm County, Sweden, NetCraftersOU (AS203273). 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 Netcraftersou?

1 other free proxy is live on Netcraftersou (AS203273) in our pool right now, alongside 91.186.217.170:3128. 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 Sweden?

Yes, 200 free proxies are exiting from Sweden in our pool right now, answering in 641ms at the median. If this address is not usable, that list is the place to look for a working one.

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).
