How HProxy checks 51.15.19.34:8888
HProxy has checked 51.15.19.34:8888 256 times and it answered 57 of those. Every one of those was a real connection attempt, never a lookup.
42 public sources published it
51.15.19.34 appears in 42 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 8888: HTTP, alternate
Port 8888 is another common stand-in for port 80, and the default for several debugging and proxy-inspection tools. Seeing it usually says more about the software than about the host.
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 51.15.19.34:8888 and gives it up to 90 seconds to answer. Slow is not the same as dead, 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, so a proxy is never missed because we guessed the wrong protocol.
256 checks, 57 answered
That is 22% of the time, measured since July 15, 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. 51.15.19.34:8888 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 7, 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 6 other free proxies on Onlinenet Dedicated, and 84 in Netherlands. 51.15.19.34:8888 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
How many free proxies are on ONLINE_NET_DEDICATED_SERVERS_NL
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 620 addresses on AS12876, which is 0.11% of every address in the database and a meaningful pocket of the database. That makes it the 73rd largest source of free proxies of every network we have ever seen. 6 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 51.15.19.34:8888
Is 51.15.19.34:8888 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 16, 2026. We still re-test it periodically in case it returns.
Was 51.15.19.34 ever actually a proxy?
Yes. We ran 256 checks against it and it answered 57 of them, about 22% of the time, over 1 day on our list.
Where was 51.15.19.34 hosted?
Netherlands, ONLINE_NET_DEDICATED_SERVERS_NL (AS12876). 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 Onlinenet Dedicated?
6 other free proxies are live on Onlinenet Dedicated (AS12876) in our pool right now, alongside 51.15.19.34:8888. 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 Netherlands?
Yes, 84 free proxies are exiting from Netherlands in our pool right now, answering in 934ms 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).
