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 3 other free proxies on Hostkey AS, and 322 in Germany. 91.239.211.113:3128 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 18987ms it is slower than the 54ms median for Germany proxies.

HOSTKEY-AS is the 138th 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 274 addresses on AS57043, which is 0.05% of every address in the database and a small corner of the database. That makes it the 138th largest source of free proxies of every network we have ever seen. 4 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.

How HProxy checks 91.239.211.113:3128

91.239.211.113:3128 is in the live pool right now, and it stays there only for as long as it keeps answering.

  1. 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.

  2. 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 91.239.211.113:3128 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, which is how we know it spoke HTTP.

  3. 176 checks, 75 answered

    That is 43% of the time, measured since August 6, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.

  4. It is being re-tested continuously

    91.239.211.113:3128 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 91.239.211.113?

It speaks HTTP, and our checks grade it elite. The port is 3128. Point your client at 91.239.211.113:3128 over http to route a request through it.

Where is 91.239.211.113 located?

Traffic through it exits from Frankfurt am Main, Germany, on HOSTKEY-AS (AS57043). That is where the destination site will think your request came from.

How fast is 91.239.211.113:3128?

It answered in 18987ms on the last check. Free public proxies are shared, so real-world speed varies with how many other people are using it at the same moment.

How reliable has 91.239.211.113:3128 been?

Is it safe to use 91.239.211.113:3128?

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 Hostkey AS?

3 other free proxies are live on Hostkey AS (AS57043) in our pool right now, alongside 91.239.211.113:3128. Networks that host one open proxy usually host several, which is why the whole AS is worth browsing rather than just this address.

91.239.211.113:3128 answers 43% of the time, and that is ordinary for a public proxy. Nothing here is a service anybody sells you, which is why the numbers swing and why the list turns over constantly.

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).
