Where this address sits
Right now our free pool holds 3 other free proxies on Net2atlanta, and 3,048 in United States. 199.66.182.232:4145 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 900ms it answers faster than the 2547ms median for United States proxies (about 35% of it).
How many free proxies are on NET2ATLANTA.COM LLC
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 14 addresses on AS20081, which is 0.00% of every address in the database and a small corner of the database. 4 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.

Continuous monitoring
How HProxy checks 199.66.182.232:4145
199.66.182.232:4145 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 4145: SOCKS4, common
Port 4145 is everywhere in free proxy lists, nearly always as SOCKS4. No standards body ever gave it that job. It stuck because everyone copied everyone else, so treat the number as a strong hint rather than a promise.
It has answered every single check
Each check opens a real connection to 199.66.182.232:4145 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. 199.66.182.232:4145 has completed that handshake on all 41 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 SOCKS4 and SOCKS5.
41 checks, 41 answered
That is 100% of the time, measured since August 21, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
199.66.182.232:4145 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.

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).
