How HProxy checks 104.237.152.124:3129

104.237.152.124:3129 is in the live pool right now, and it stays there only for as long as it keeps answering. Here is exactly what HProxy does to it, and how often.

  1. Port 3129: Squid, second instance

    Port 3129 is the conventional second Squid port, commonly used for a transparent or intercepting instance running alongside the one on 3128.

  2. Every check is a real connection

    HProxy does not read this address off somebody else's list and pass it on. Each check opens an actual connection to 104.237.152.124:3129 and waits up to 4 seconds for the other end to complete a proxy handshake. 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 HTTP.

  3. 3,047 checks, 2,975 answered

    That is 98% of the time, measured since June 23, 2026. Every one of those results, successes and failures alike, is a connection HProxy opened itself.

  4. It is being re-tested continuously

    104.237.152.124:3129 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.

Where this address sits

Right now our free pool holds 11 other free proxies on Akamai, and 1,072 in United States. 104.237.152.124:3129 sits inside that set, so if it is not usable the pages below are where its closest alternatives are. At 2200ms it is slower than the 2146ms median for United States proxies.

What HProxy holds on Akamai Technologies, Inc.

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 947 addresses on AS63949, which is 0.16% of every address in the database and a meaningful pocket of the database. 25 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.

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). Full details on the report abuse page.
