How this one compares
It was one of the good ones, for 6 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 8,765 proxies answering right now, the middle of the pack answers 13.8% of the checks we send it.

HProxy has opened 650 real connections to this endpoint in total. The sweep reaches every address in the database roughly once every 24 hours.
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 189.39.123.155:8083
HProxy has checked 189.39.123.155:8083 650 times and it answered 397 of those. Every one of those was a real connection attempt, never a lookup.
47 public sources published it
189.39.123.155 appears in 47 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 8083: 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.
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 189.39.123.155:8083 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.
650 checks, 397 answered
That is 61% of the time, measured since July 17, 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. 189.39.123.155:8083 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 13, 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.

Live free proxies right now
View all →Where this address sits
Right now our free pool holds 1 other free proxy on Algar S, and 226 in Brazil. 189.39.123.155:8083 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 ALGAR TELECOM S/A
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 80 addresses on AS16735, which is 0.01% of every address in the database and a small corner of the database. 1 of them is 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 189.39.123.155:8083
Is 189.39.123.155:8083 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 23, 2026. We still re-test it periodically in case it returns.
Was 189.39.123.155 ever actually a proxy?
Yes. We ran 650 checks against it and it answered 397 of them, about 61% of the time, over 6 days on our list.
What is the hostname for 189.39.123.155?
Its reverse DNS record is 155.123.39.189.smart.net.br. 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 189.39.123.155 hosted?
Recife, Pernambuco, Brazil, ALGAR TELECOM S/A (AS16735). 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 Algar S?
1 other free proxy is live on Algar S (AS16735) in our pool right now, alongside 189.39.123.155:8083. 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 Brazil?
Yes, 226 free proxies are exiting from Brazil in our pool right now, answering in 1311ms 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).
