How HProxy checks 51.49.153.183:57565
HProxy has opened a connection to 51.49.153.183:57565 7 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.
4 public sources published it
51.49.153.183 appears in 4 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 57565: Ephemeral port range
This port sits in the ephemeral range, the block an operating system hands out temporarily for outgoing connections. A proxy advertised on one of these is usually a short-lived forward, often a home router mapping or a NAT translation, and it commonly stops working after a reboot or a lease change. That is a large part of why so many addresses in public lists never answer.
Every failure here was measured, not assumed
Each check opens an actual connection to 51.49.153.183:57565 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. 7 times HProxy tried, and 7 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.
7 checks, zero connections
Not one of those 7 attempts reached a working proxy. The address stays in the database with that result attached, because "we tried 7 times and it never answered" is a far more useful answer than silence for anyone who found 51.49.153.183 somewhere and wants to know what it is.
It is still re-tested every 24 hours
51.49.153.183:57565 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 4,421 other free proxies on Amazon, and 69 in Spain. 51.49.153.183:57565 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
What HProxy holds on Amazon.com, Inc.
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 6,997 addresses on AS16509, which is 1.2% of every address in the database and a substantial share of everything HProxy tracks. 16,108 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 51.49.153.183:57565
Is 51.49.153.183:57565 a working proxy?
No. 51.49.153.183:57565 was published as a public proxy by our sources, but across 7 checks it never once resolved to a connectable proxy.
Was 51.49.153.183 ever actually a proxy?
It was listed as one, but no. 7 checks, zero successful connections. Plenty of "free proxy" lists republish addresses without ever testing them.
Where was 51.49.153.183 hosted?
Spain — Amazon.com, Inc. (AS16509). 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 Amazon?
4,421 other free proxies are live on Amazon (AS16509) in our pool right now, alongside 51.49.153.183:57565. 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 Spain?
Yes, 69 free proxies are exiting from Spain in our pool right now, answering in 122ms 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).
