Where this address sits
Right now our free pool holds 111 other free proxies on M247, and 5,430 in United States. 45.74.31.42:4757 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 10031ms it is slower than the 4950ms median for United States proxies.
M247 is the 7th 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 13,330 addresses on AS9009, which is 2.0% of every address in the database and a substantial share of everything HProxy tracks. That makes it the 7th largest source of free proxies of every network we have ever seen. 112 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 45.74.31.42:4757
45.74.31.42:4757 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 4757: Registered port range
This port sits in the middle range, where any ordinary program can listen without special permission. The number itself carries no reserved meaning, which tells you somebody picked it on purpose instead of accepting a default.
It has answered every single check
Each check opens a real connection to 45.74.31.42:4757 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. 45.74.31.42:4757 has completed that handshake on all 7 attempts so far, which is rare on a free public proxy and worth treating with some suspicion until the record is longer. The handshake is attempted across HTTP, HTTPS, SOCKS4 and SOCKS5, which is how we know it spoke SOCKS5.
7 checks, 7 answered
That is 100% of the time, measured since August 26, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
45.74.31.42:4757 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.

Is it safe to use 45.74.31.42:4757?
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.

This one is good, and it will still disappear.
45.74.31.42:4757 has answered 100% of our checks, which puts it well above most of what we track.

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).
