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 87.251.77.29:3128
87.251.77.29:3128 has been through 1,622 checks on HProxy's list, answering 1,392 of them. Few addresses in the database carry a record this long.
19 public sources published it
87.251.77.29 appears in 19 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 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.
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 87.251.77.29:3128 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.
1,622 checks, 1,392 answered
That is 86% of the time, measured since July 5, 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. 87.251.77.29:3128 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 12 hours. Its last check was on September 8, 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 6 other free proxies on CHSL ONE, and 1,272 in Germany. 87.251.77.29:3128 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 CHSL-ONE
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 91 addresses on AS210546, which is 0.01% of every address in the database and a small corner of the database. 6 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 87.251.77.29:3128
Is 87.251.77.29:3128 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 September 2, 2026. We still re-test it periodically in case it returns.
Was 87.251.77.29 ever actually a proxy?
Yes. We ran 1,622 checks against it and it answered 1,392 of them, about 86% of the time, over 59 days on our list.
What is the hostname for 87.251.77.29?
87.251.77.29 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 87.251.77.29 hosted?
Frankfurt am Main, Hesse, Germany, CHSL-ONE (AS210546). 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 CHSL ONE?
6 other free proxies are live on CHSL ONE (AS210546) in our pool right now, alongside 87.251.77.29:3128. 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 Germany?
Yes, 1,272 free proxies are exiting from Germany in our pool right now, answering in 37ms 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).
