    I did the same question in another forum but didn't recive any replay, hope here to have better luck.

    When you do a ip range scan and you obtain for ex. 2000 proxy, does this list of proxy good to be checked everyday ? (so no necessary to scan again this range) or need to renew the scan everyday before any new check?

    My guess is that this list of proxies would mainly consist of infected computers that have a trojan + proxy installed. Since its easy to crack a consumer grade box (Windows, Mac) those proxies will most probably go up and down by the hour. So a list of 2000 proxies can be gone in the span of hours (think: antivirus signature update). But this is only my guess, I've never scraped proxies myself.

    i already ans you on proxyfire forum :) ..

    if you scan the proxies on any range after that you have to test to the proxies on any gud HTTP tester
    to see how much you get gud proxies on the tester.That is necessary to test the proxies after you scan the proxies..
    Port scan proxy r public proxies not private proxies and public proxies must be dead after few hours or some mints...

    you cant get 100% result if your range is weak..
    for ex : you scan 100 proxies.when you test the proxies on the tester and tester result is show
    100 out of 40 or 50 proxies r dead..
    if you think that your range is strong and gud for scanning then you get nice result 90- 100% result
    Every time you scan and after to test the proxies any nice HTTP Tester then use it gud proxies :)



    he talking about port scanning not botnet or scraped useless proxies:)

    you also need to check your proxys with a honey pot tester
    as not mentioned above - you need to check the proxys

    "honeypot" it's a mischievous way of using what is advertised as a
    "secure" HTTPS proxy server, yet they log all your activity and either
    use it as information for spamming your email among other possible
    reasons and mischievous uses. so always check

    It depends on the ISP. I'll give you some actual useful info, cuz I don't know know what they're trying to tell you, and maybe you can understand that, but that was pure jibberish to me. Some ISP's have open ports to their proxies. That means that they'll always have open proxies. So for example, you scan an ISP from Brazil named Global Village Telecom you'll always fine some open proxies. You would need to rescan those ranges everyday though, because some of the computers with open ports may not be powered on at that moment, or, they might be DSL lines. In that case the IPs would change every so often. In any event, you're best bet is to build a good list of ranges that you can find good proxies on, and scan them each day. If you're using something like Proxyfire then yes, you'll have to recheck those. My advice though would be to just get a good checker that doesn't require that.

    Edit: Meant to mention this, you'll want to filter those IPs as Proxygo has said as well. Depending on what you're doing, you can run into a lot of trouble, or even give away your method by using open-proxies like that, so you definitely need to be careful.

    I don't know if I got what you mean, but when I scan or use the proxy I always put my computer behind a good VPN for security reasons.
    Anyway I filter the range before to scan to avoid forbidden and dangerous proxy.

    Now you cleared me why often scanning some range I can find 1500 Ip but then when I go to check only 30 are open proxy, of course this isn't a good range.
    Yes for scan I use proxyfire, I find it handy and usefull also for quickly build some range.
    About security topic, same as told above to proxygo.
    What you mean for: "My advice though would be to just get a good checker that doesn't require that" ?

    Thanks to both for info and hints

    You will need to redo it daily as they would be accessible to everyone else.

    Proxyfire requires you to double check your proxies. Not only is it annoying, but it's a waste of time. I have a custom scanning solution I found that allows me to scan around 45-50k IPs per minute on a good host, and I don't have to check them again after. I'm not sure if Proxyfire is only checking for a response, or what exactly. Could be that it just takes so long that half are dead by the time you go back and recheck them, but in any event if you look around hard enough you'll find some checkers out there that will accomplish what mine does. I agree though, Proxyfire does come in handy for range generation.

    as a retired proxyfire admin i havnt work on proxyfire in 5 yrs but
    from what i remember proxyfire just looks for a response
    which is why when you scan a list of ip blocks u have to test them
    in a proxy checker, and my guess is cash is using syn proxy scanning
    which for me never worked well, tcp scanning was always more
    reliable for me

    Yes, when you scan, proxyfire can only get the response from the Ip but not check, and also for me syn don't work (i don't know if need some specific setting in the network setting), so I use too tcp method.
    I know that http proxy scanner is a good tool for scan, but it use sync method too and not work on my side.
