How this one compares
It was one of the good ones, for 10 days.
Every free proxy list quotes an uptime figure. Almost none of them tell you what a normal one looks like, so here is ours: across the 4,737 proxies answering right now, the middle of the pack answers 14.9% of the checks we send it.

What normal looks like
Every number above is measured against these two.
A percentage on a proxy list means nothing without the shape of the thing it came from. These are the two distributions the rest of this page compares against, drawn from HProxy's own checks rather than from anybody's marketing page.

How HProxy checks 100.52.49.226:3128
HProxy has checked 100.52.49.226:3128 829 times and it answered 170 of those. Every one of those was a real connection attempt, never a lookup.
41 public sources published it
100.52.49.226 appears in 41 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 3128: Squid default
Port 3128 is the default for Squid, the most widely installed proxy software in the world. Most addresses published on 3128 are Squid servers that were meant to serve one office or one network and ended up reachable by everybody.
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 100.52.49.226:3128 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, so a proxy is never missed because we guessed the wrong protocol.
829 checks, 170 answered
That is 21% of the time, measured since June 20, 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. 100.52.49.226:3128 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 18, 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 42 other free proxies on Amazon, and 884 in United States. 100.52.49.226:3128 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
Amazon.com, Inc. is the 50th 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 1,017 addresses on AS14618, which is 0.17% of every address in the database and a meaningful pocket of the database. That makes it the 50th largest source of free proxies of every network we have ever seen. 42 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 100.52.49.226:3128
Is 100.52.49.226:3128 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 June 30, 2026. We still re-test it periodically in case it returns.
Was 100.52.49.226 ever actually a proxy?
Yes. We ran 829 checks against it and it answered 170 of them, about 21% of the time, over 10 days on our list.
What is the hostname for 100.52.49.226?
Its reverse DNS record is ec2-100-52-49-226.compute-1.amazonaws.com. That is what the address itself publishes about who operates it, which is often more telling than the network name: hosting providers name their machines by region and instance type, and a residential line usually carries its ISP's own pattern.
Where was 100.52.49.226 hosted?
Ashburn, Virginia, United States, Amazon.com, Inc. (AS14618). 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?
42 other free proxies are live on Amazon (AS14618) in our pool right now, alongside 100.52.49.226:3128. 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, 884 free proxies are exiting from United States in our pool right now, answering in 1517ms 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).
