Where this address sits
Right now our free pool holds 1,476 other free proxies on Secured Servers, and 24,331 in United States. 131.153.163.138:56280 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 601ms it answers faster than the 10315ms median for United States proxies (about 6% of it).
SECURED SERVERS LLC is the 2nd 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 45,237 addresses on AS19437, which is 6.5% of every address in the database and a substantial share of everything HProxy tracks. That makes it the 2nd largest source of free proxies of every network we have ever seen. 1,477 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 131.153.163.138:56280
131.153.163.138:56280 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 56280: Ephemeral port range
This is a throwaway port number, the kind a computer hands out for a few minutes and then takes back. Anything published on one tends to move or disappear when its host restarts, which is a large part of why public proxy lists rot so fast.
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 131.153.163.138:56280 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 and HTTPS and SOCKS5.
It is being re-tested continuously
131.153.163.138:56280 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 131.153.163.138?
It speaks HTTP, HTTPS, SOCKS5, and our checks grade it elite. The port is 56280. Point your client at 131.153.163.138:56280 over http to route a request through it.
Where is 131.153.163.138 located?
Traffic through it exits from Ashburn, United States, on SECURED SERVERS LLC (AS19437). That is where the destination site will think your request came from.
How fast is 131.153.163.138:56280?

Is it safe to use 131.153.163.138:56280?
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 Secured Servers?
1,476 other free proxies are live on Secured Servers (AS19437) in our pool right now, alongside 131.153.163.138:56280. Networks that host one open proxy usually host several, which is why the whole AS is worth browsing rather than just this address.

This one is good, and it will still disappear.
131.153.163.138:56280 has answered 100% of our checks, which puts it well above most of what we track.

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).
