How HProxy checks 199.66.182.243:145
HProxy has opened a connection to 199.66.182.243:145 6 times and it has never once answered. That is a measurement, not an assumption, and it is the difference between this record and the lists that republished the address without testing it.
4 public sources published it
199.66.182.243 appears in 4 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 145: System port
Ports below 1024 are privileged: on most operating systems a program needs administrator rights to listen on one. Whatever answered here was therefore started by a system service or by someone with full control of the machine, not by an ordinary user process.
Every failure here was measured, not assumed
Each check opens an actual connection to 199.66.182.243:145 and waits up to 4 seconds for the other end to complete a proxy handshake. Nothing about this record is inherited from the list that published the address. 6 times HProxy tried, and 6 times the connection did not complete inside that budget, which is why the answer on this page is a flat no rather than a maybe. The handshake is attempted across HTTP, HTTPS, SOCKS4 and SOCKS5, so a proxy is never missed because we guessed the wrong protocol.
6 checks, zero connections
Not one of those 6 attempts reached a working proxy. The address stays in the database with that result attached, because "we tried 6 times and it never answered" is a far more useful answer than silence for anyone who found 199.66.182.243 somewhere and wants to know what it is.
It is still re-tested every 24 hours
199.66.182.243:145 has never answered, and it is still in the rotation anyway. The sweep reaches every address in the database roughly once every 24 hours regardless of its history, because an address that was dark for months can be brought back online by whoever controls it without telling anybody. Its last check was on August 3, 2026, so the next one is due within a day of that. If that ever happens here, this page changes on its own.

Where this address sits
Right now our free pool holds 3 other free proxies on Net2atlanta, and 961 in United States. 199.66.182.243:145 sits inside that set, so if it is not usable the pages below are where its closest alternatives are.
What HProxy holds on NET2ATLANTA.COM LLC
Open proxies are not spread evenly across the internet. They cluster, because one misconfigured template, one cheap hosting reseller or one leaked image tends to produce hundreds of identical machines on the same network. HProxy tracks 10 addresses on AS20081, which is 0.00% of every address in the database and a small corner of the database. 3 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 199.66.182.243:145
Is 199.66.182.243:145 a working proxy?
No. 199.66.182.243:145 was published as a public proxy by our sources, but across 6 checks it never once resolved to a connectable proxy.
Was 199.66.182.243 ever actually a proxy?
It was listed as one, but no. 6 checks, zero successful connections. Plenty of "free proxy" lists republish addresses without ever testing them.
Where was 199.66.182.243 hosted?
United States — NET2ATLANTA.COM LLC (AS20081). 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 Net2atlanta?
3 other free proxies are live on Net2atlanta (AS20081) in our pool right now, alongside 199.66.182.243:145. 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, 961 free proxies are exiting from United States in our pool right now, answering in 895ms 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).
