Free SYN proxies. Checked every few minutes.
Every address we have ever seen running an open proxy on SYN, continuously re-verified so the list is current rather than a stale dump.

A free proxy that answered a minute ago can be gone now, which is why both numbers are here rather than one. Paid syn-grade alternatives start at $0.44/GB.
Why the dead addresses are listed too
Most free-proxy sites show you what answered on the last sweep and quietly drop everything else, which makes a network look empty on a bad day and hides the thing you probably wanted to know: whether proxies keep appearing on SYN at all. We hold 2,259 addresses on this operator and 6 of them are answering right now. Both numbers are true and only one of them is useful on its own.
What a SYN address is and is not
An autonomous system number identifies a network run as one unit. When a proxy sits on SYN, the machine hosting it lives inside that operator's address space, which is what a site sees when you connect. Filtering by network is useful when you specifically want, or specifically want to avoid, one provider's addresses. It says nothing about whether any individual address is fast, private or still alive in a minute.
Questions about SYN proxies
Are there free SYN proxies right now?
Yes. 6 addresses on SYN answered our most recent checks, out of 2,259 we hold on the operator. The sample on this page links straight to their live records.
How many SYN addresses does HProxy track?
2,259 that have answered at least once, across one autonomous system (AS64080). Each address keeps a permanent page with its full check history, whether or not it still answers.
Why does this page count addresses that no longer answer?
Because "does SYN keep producing open proxies" is the question an operator page can actually answer, and a live-only snapshot cannot. 2,253 of the addresses we hold here answered before and are silent now; we say so next to every one rather than dressing any of them up as live.
What network is behind SYN?
AS64080. An autonomous system is a network run as one unit; when a proxy sits on SYN, the machine hosting it lives inside that operator's address space, and that is what the destination site sees.
Is a free SYN proxy safe to use?
Treat it like any public proxy: shared with strangers, run by someone you have no agreement with, and liable to vanish without notice. Fine for a geo check or low-stakes research, never for logins or payments. For work that has to keep running, paid proxies start at $0.44/GB.
