The ability to block smartphonesNot planned
An option to block smartphones from being able to use a network being controlled by OpenDNS.
Whenever I have a blocked site I need to access from my cell, I revert to 4G, circumventing OpenDNS. That works for temporary situations.
If you want a more permanent solution, you can define your preferred DNS service directly on your Android phone. Depending upon your phone and android version, you may be able to define your DNS servers by going to Settings/Wireless/WiFi Settings/Advanced (this last section is menu accessed). Use a Static IP from your router's range (enter it here), and then enter your preferred DNS servers. If you want to bypass OpenDNS, you might use Google DNS (184.108.40.206, 220.127.116.11). To flush your DNS caches, reboot or restart your phone.
Alternately you can install SetDNS (for example) from the Play Store. You do not require a rooted phone to use its DNS setting capability. Again you might use Google DNS (18.104.22.168, 22.214.171.124). If you like the app, you'll want to buy the paid version to get full 24/7 DNS control.
Thanks for the info. What we're looking for is not for an individual phone. We have a wifi at our resident camp and we are needing to block the campers from connecting their phones to our wifi to keep from eating up all our bandwidth.
So I'm not sure if there are ports or urls that can be blocked on the router to keep them from accessing services on there phones.
I've been told that if our wifi had an acceptance of use page that they would not be able to connect to the network.
Blocking leechers is an entirely different topic (ha, I really missed that), and has nothing to do with OpenDNS. That said, the simplest/safest/surest router implementation would be to use WPA2 (or WPA, but not WEP) encryption (w/passphrase) for staff-only use. You should have this capability built-in to your router. When your authorized users log in to your wireless network for the first time, their cell phones should "remember" the passphrase authorization for all future connections.
Assuming you don't distribute or leak out your passphrase, campers will be denied access. It's probably a good practice to change passphrases monthly in your situation.
