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.

Where this address sits
Right now our free pool holds 5 other free proxies on CHSL ONE, and 267 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. At 964ms it answers faster than the 1240ms median for Germany proxies (about 78% of it).
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 75 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.

Continuous monitoring
How HProxy checks 87.251.77.29:3128
87.251.77.29:3128 is in the live pool right now, and it stays there only for as long as it keeps answering.
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, which is how we know it spoke HTTP.
431 checks, 404 answered
That is 94% of the time, measured since August 11, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
87.251.77.29:3128 is in the live rotation, so it is re-tested continuously rather than on a daily cycle. If it stops answering it is marked down immediately, and if it stays down for 3 days it moves into the public proxy database with its full record intact. Nothing is deleted at any point.

What kind of proxy is 87.251.77.29?
It speaks HTTP. The port is 3128. Point your client at 87.251.77.29:3128 over http to route a request through it.
Where is 87.251.77.29 located?
Traffic through it exits from Frankfurt am Main, Germany, on CHSL-ONE (AS210546). That is where the destination site will think your request came from.
How fast is 87.251.77.29:3128?

Across 8 days of tracking it answered 94% of our checks. The chart on this page shows every day we have recorded for it, including the days it was down.
Is it safe to use 87.251.77.29:3128?
Treat it the way you would any public proxy: it is operated by someone we have no relationship with, it is shared with strangers, and anything you send unencrypted over it can be read. Fine for a quick geo check or a scrape of public data, never for logins, payments or anything private.
How many free proxies are on CHSL ONE?
5 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.

Upgrade to the paid network
This one is good, and it will still disappear.
87.251.77.29:3128 has answered 94% of our checks, which puts it well above most of what we track. It is still a public endpoint with nobody standing behind it: nobody agreed to serve you, no capacity is set aside for you, and there is no warning on the day it stops. Fine for a test, a bad foundation for anything that has to work tomorrow.

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).
