How HProxy checks 131.153.163.133:8888
HProxy has opened a connection to 131.153.163.133:8888 8 times and it has never once answered. That is a measurement, not an assumption, and it is the difference between this record and the lists that republished the address without testing it.
One public source published it
131.153.163.133 reached HProxy through a single public proxy source. Being published on a list is a claim that an address works. It is not a test, and nobody on that chain is obliged to have tried it.
Port 8888: HTTP, alternate
Port 8888 is another widely used unprivileged HTTP alternate. It is also the default for several debugging proxies, so addresses here are often development tooling that was left exposed.
Every failure here was measured, not assumed
Each check opens an actual connection to 131.153.163.133:8888 and waits up to 4 seconds for the other end to complete a proxy handshake. Nothing about this record is inherited from the list that published the address. 8 times HProxy tried, and 8 times the connection did not complete inside that budget, which is why the answer on this page is a flat no rather than a maybe. The handshake is attempted across HTTP, HTTPS, SOCKS4 and SOCKS5, so a proxy is never missed because we guessed the wrong protocol.
8 checks, zero connections
Not one of those 8 attempts reached a working proxy. The address stays in the database with that result attached, because "we tried 8 times and it never answered" is a far more useful answer than silence for anyone who found 131.153.163.133 somewhere and wants to know what it is.
It is still re-tested every 24 hours
131.153.163.133:8888 has never answered, and it is still in the rotation anyway. The sweep reaches every address in the database roughly once every 24 hours regardless of its history, because an address that was dark for months can be brought back online by whoever controls it without telling anybody. Its last check was on August 3, 2026, so the next one is due within a day of that. If that ever happens here, this page changes on its own.

Where this address sits
Right now our free pool holds 41 other free proxies on Secured Servers, and 949 in United States. 131.153.163.133:8888 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
What HProxy holds on SECURED SERVERS LLC
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 1,552 addresses on AS19437, which is 0.27% of every address in the database and a meaningful pocket of the database. 365 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 131.153.163.133:8888
Is 131.153.163.133:8888 a working proxy?
No. 131.153.163.133:8888 was published as a public proxy by our sources, but across 8 checks it never once resolved to a connectable proxy.
Was 131.153.163.133 ever actually a proxy?
It was listed as one, but no. 8 checks, zero successful connections. Plenty of "free proxy" lists republish addresses without ever testing them.
Where was 131.153.163.133 hosted?
United States — SECURED SERVERS LLC (AS19437). 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 Secured Servers?
41 other free proxies are live on Secured Servers (AS19437) in our pool right now, alongside 131.153.163.133:8888. 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, 949 free proxies are exiting from United States in our pool right now, answering in 876ms at the median. If this address is not usable, that list is the place to look for a working one.

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).
