How HProxy checks 150.136.239.172:3128
150.136.239.172:3128 has been through 2,109 checks on HProxy's list, answering 1,015 of them. Few addresses in the database carry a record this long.
18 public sources published it
150.136.239.172 appears in 18 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 listening port for Squid, the most widely deployed caching proxy in the world. Most addresses published on 3128 are Squid installations that were left reachable from the public internet rather than restricted to a local network.
Every check is a real connection
HProxy does not read this address off somebody else's list and pass it on. Each check opens an actual connection to 150.136.239.172:3128 and waits up to 4 seconds for the other end to complete a proxy handshake. 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.
2,109 checks, 1,015 answered
That is 48% of the time, measured since May 13, 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. 150.136.239.172:3128 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 6, 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 28 other free proxies on Oracle, and 1,036 in United States. 150.136.239.172:3128 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
What HProxy holds on Oracle Corporation
Open proxies are not spread evenly across the internet. They cluster, because one misconfigured template, one cheap hosting reseller or one leaked image tends to produce hundreds of identical machines on the same network. HProxy tracks 1,205 addresses on AS31898, which is 0.21% of every address in the database and a meaningful pocket of the database. 28 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 150.136.239.172:3128
Is 150.136.239.172:3128 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 July 18, 2026. We still re-test it periodically in case it returns.
Was 150.136.239.172 ever actually a proxy?
Yes. We ran 2,109 checks against it and it answered 1,015 of them, about 48% of the time, over 2 months on our list.
Where was 150.136.239.172 hosted?
United States, Oracle Corporation (AS31898). 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 Oracle?
28 other free proxies are live on Oracle (AS31898) in our pool right now, alongside 150.136.239.172:3128. 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 United States?
Yes, 1,036 free proxies are exiting from United States in our pool right now, answering in 2178ms 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).
