Text of the page (random words):
proxy checker test any proxy in one second proxy connect proxy connect check bulk check my ip free proxies proxy checker in one second paste it below we connect through it and tell you in plain words whether it works and how well it hides you one proxy bulk check my ip proxy address check read connect tunnel headers timing reputation reading the address and port you pasted paste it your way 01 ip port 02 ip port user pass 03 user pass ip port does it connect we open a real encrypted request through the proxy not just a ping where does it land country city and network the sites you visit will actually see does it leak headers dns and 46 spam lists summed up as one verdict what you can paste 01 ip port an open proxy or one that authenticates by address 02 ip port user pass how most sellers hand them over 03 user pass ip port what most libraries and browsers expect 04 ip port user pass spaces or tabs the way they come out of a spreadsheet a prefix is optional http https socks4 and socks5 are all understood and so are the socks4a and socks5h spellings without one we try http first then socks5 then socks4 and keep the first that answers hostnames work as well as addresses ipv6 included and anything after a is treated as your own note what the check does connect a plain tcp connection to the address and port timed if nothing answers nothing else runs tunnel a real request an encrypted request through the proxy to a page we run it carries a one time token so a login portal or a web server sitting on that port cannot pass for a proxy send a plain one too unencrypted is the only place a proxy can add headers about you so that leg decides the anonymity grade measure and look up time it again read the exit address watch where the name lookups went and ask the blacklists 8 s to connect 12 s per request 4 timed probes 46 blocklists 60 s result cache those requests leave from our servers not from your machine a proxy in the same city as you will usually test slower here than it feels there and one on the other side of the world may test faster repeating an identical check inside the cache window returns the stored result rather than running it again so two clicks a few seconds apart are one measurement and not two the method in full with the arithmetic behind the score is in how the test works how to read your result the verdict the first line answers the two questions people actually arrive with does this proxy work and does it hide me everything underneath is the evidence that line was built from which is why it is worth reading even when the verdict is the one you hoped for a proxy can work perfectly and still be listed everywhere and the verdict will say so in a way a single word cannot the score out of 100 five things go into one number weighted the way they matter in use how fast it answers how much it hides whether the address already has a reputation how steady it was across the samples and whether name lookups leaked around the tunnel a proxy that never connects scores zero because there is nothing to weigh speed 30 anonymity 28 reputation 20 steadiness 12 dns 10 speed we time the proxy 4 times and report the median the slow tail the spread between the samples and every individual figure the spread is worth as much as the median a proxy that averages well but jumps around will sail through some requests and stall on others which is harder to work with than one that is evenly slow the bands below are the ones the verdict uses fast under 120 ms slow very slow over 500 ms when it fails a failed check names its cause instead of just calling the proxy dead because what you do next depends entirely on which of them it was one of these means the proxy is gone two mean it is alive and unwilling and one means the proxy is fine and your credentials are not these are the five you will see refused nothing was listening on that port timed out it accepted the connection and never answered needs a login the proxy wants a username and password or rejected the ones given the credentials are the problem not the proxy returned an error it forwarded the request and the far end refused it not a proxy something answered but not in a proxy protocol the address you pasted and the address that came out 198 51 100 24 what you paste the proxy entry then exit 203 0 113 88 what websites see you connect to one machine and traffic leaves from another gateway and rotating proxies work that way by design a proxy sold as a single static address should not so we flag it when the two differ how well it hides you the grade comes from what actually reached our page never from what the proxy was sold as the report lists every header that arrived with the request so the difference between these three rows is always something you can point at usually a single header carrying either nothing the proxy s own name or your address fully nothing in the request marked it as proxied barely the proxy announced itself some sites block on that alone not at all your own address was forwarded along with the request where it lands country city network and local time at the exit read from the db ip databases we keep on our own machines checkers that query a third party api will sometimes disagree with us and with each other since no two location databases are updated on the same day spam and abuse lists we ask 46 public lists each answer arrives with the return code the list sent what that code means in the operator s own documentation what it cost in points and where to ask for removal refusals a rate limit or a list declining queries from public resolvers are recorded as no answer rather than as a listing dns whether name lookups went through the tunnel or around it a proxy can hide your address and still hand your own resolver every hostname you visit what we cannot tell you nothing about your own browser no webrtc or dns leak test on this page those measure your connection rather than the proxy s and live on check my ip no bought fraud score some checkers show one from a commercial vendor which means every address tested is forwarded to that vendor ours comes from lists that publish their own rules no verdict on a given website we test our own page whether a shop a bank or a streaming service accepts an address is decided with data nobody publishes what happens to the proxy you paste the report keeps the address and the port usernames and passwords are masked out of everything shown and everything stored the password opens the test connection and is then dropped reports live at their own link for 30 days those links carry noindex and are disallowed to crawlers but anyone holding one can read the report privacy has the details frequently asked questions how does this proxy checker actually test a proxy it sends a request through the proxy to a page we run and reads what that page received a checker that only opens a socket will pass a proxy that accepts connections and forwards nothing which proxy formats can i paste ip port ip port user pass user pass ip port and the same fields separated by spaces or tabs a protocol prefix is optional and anything after a is treated as your own note which protocols do you support http https socks4 and socks5 including the socks4a and socks5h spellings with no prefix we try http first then socks5 then socks4 and keep the first that answers what do elite anonymous and transparent mean elite nothing in the request marked it as proxied anonymous the destination can tell a proxy is in use but not who you are transparent your own address was forwarded the grade comes from the headers that arrived at our page why does another checker say this proxy works and you say it does not usually because they opened a socket and we sent a request through it sometimes because the proxy forwards plain http but will not tunnel or because it died between the two checks the failure line says which how accurate is this what we measure ourselves is exact for the moment of the test the connection the timings the headers that arrived the exit address location comes from a database and can be a city out blacklist answers are the lists opinions and a free proxy can change state between two checks a minute apart why is the exit address different from the address i pasted you connect to one machine and traffic leaves from another gateway and rotating proxies work that way by design a proxy sold to you as a single static address should not so it is worth asking the seller about is it free and how many checks can i run free with no account up to 20 single checks a minute from one address and up to 500 proxies in one bulk run do you store the proxies i paste the address and port for 30 days so the report link keeps working never the password and never the username in readable form where to go next bulk a whole list at once up to 500 a run streaming back as each one finishes check my ip your own connection with no proxy in the way
