Blocking Proxy/VPN on Android

    You search the internet to find out what domain names or IP addresses are being used by Opera VPN on Android.  What else?

    Look here: http://bfy.tw/EhzK

    Ok, I took over this task for you as an exception to see if this tip is worthy enough to be posted.

    Here is what I easily found (one of the first result in the search list):
    https://gist.github.com/spaze/558b7c4cd81afa7c857381254ae7bd10

    It mentions domain names which you can add now to your "always block" list:

    • api.surfeasy.com
    • de0.opera-proxy.net

    You even can add just surfeasy.com and opera-proxy.net which cover these and all their possible subdomains.

    So, do you know now what to do next time?

    So, now the surprise: these domains are already categorized as Proxy/Anonymizer which indicates that your problem is in fact of a different nature.

    For example: are you using OpenDNS at all? Visit http://welcome.opendns.com/ with this Android device.  If you are not using OpenDNS, then there is no way that OpenDNS can do anything for you.  You must use OpenDNS to use it.  ;-)

    If you're in fact using OpenDNS: what DNS resolver addresses do you have configured, the normal ones or the FamilyShield addresses?  The latter block Proxy/Anonymizer by default.  The normal ones require your IP address being registered at your dashboard and the category being blocked.

    There are possible other reasons why it may not work on this device, for example that Opera VPN does not use the DNS service configured by you, but its own DNS service.  This again means that you're not using OpenDNS.  It looks like you have to uninstall the app and to block Google Play to prevent from downloading it going further.

    I have already googled and blocked those domains as you have mentioned. I wouldn't have come to this forum if I didn't exhaust any other option which would permit me. OpenDNS is configured on the network and is used as the resolver for all connected devices. I blocked opera.com as well but it is to no avail.

    "OpenDNS is configured on the network and is used as the resolver for all connected devices."

    How did you prove this?  Did you visit http://welcome.opendns.com/ with this Android device?  What was the message?

    The first screenshot is without Opera VPN activated.

    The second screenshot is where Opera VPN has been activated.

    As I said above, and as you can see now, this Android device doesn't use OpenDNS as long as the VPN is enabled.  And as long as you do not use OpenDNS, any related settings cannot take effect, and OpenDNS can do nothing for you.

    And as I said too, it looks like you have to uninstall the app and to block Google Play to prevent from downloading the app going further if you do not want to use Opera VPN.  With OpenDNS you can block only domains, not apps, cars, flowers or any other objects.  Another approach would be to block IP addresses or ranges and ports at the router level, but this is unrelated to OpenDNS.
