Where this address sits
Right now our free pool holds 3 other free proxies on AT&T, and 24,159 in United States. 99.56.147.242:56250 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 3394ms it is slower than the 2603ms median for United States proxies.
AT&T Enterprises, LLC is the 125th 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 401 addresses on AS7018, which is 0.05% of every address in the database and a small corner of the database. That makes it the 125th largest source of free proxies of every network we have ever seen. 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.

How HProxy checks 99.56.147.242:56250
99.56.147.242:56250 is in the live pool right now, and it stays there only for as long as it keeps answering.
Port 56250: Ephemeral port range
This is a throwaway port number, the kind a computer hands out for a few minutes and then takes back. Anything published on one tends to move or disappear when its host restarts, which is a large part of why public proxy lists rot so fast.
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 99.56.147.242:56250 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, which is how we know it spoke HTTPS.
5,158 checks, 2,726 answered
That is 53% of the time, measured since June 14, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.
It is being re-tested continuously
99.56.147.242:56250 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).
