Can you please suggest a DNS filtering software?

Tejas July 12, 2013

There is a need to set up an open WiFi network within a college campus. It is essential that all types of adult content and social media be blocked, no matter which device [Android, iPhone, laptops, any OS] connects to the network.

Please provide the information about a DNS blocking software, which serves this purpose. I appreciate any other types of suggestion, which would serve this purpose. And I also want to see to that no device connects to a blocked website using a proxy server. Please respond ASAP.

    Bruce's suggestion is great, and there isn't any software that would be installed. Many businesses, colleges and schools, and home users rely on the DNS server blocking capabilities, dashboard view of the content being accessed and blocked, as well as being able to block or whitelist content through the account on a web browser from virtually any computer at any time. There are limitations to OpenDNS, so I would only use it as a supplement to another content blocker, which I recommend K-9 Web Protection, also used by colleges and schools, businesses, and home users.

      Sorry, K9 Web Protection has to be installed on every PC and Mac to work, and Android, iOS, and Windows Phone would need the K9 Web Browser. This would not be the best if you are wanting to block people from accessing certain content if you do not have permission to access individual devices. I did find this device that looks to be promising, though:

    Configure your firewall to only allow DNS requests from your DNS servers. (I am assuming that your have your own DNS servers that are acting as forwarders for non-local systems.) Set up your DNS servers to use OpenDNS and enable filtering for adult content and proxies/anonymizers on your OpenDNS network account. They have filters for a few dozen categories that you can selective enable and disable. This should block most of the activity you have specified (I don't know of any filtering software that is 100% accurate in its blocking capabilities).
