    Using openDNS I can specify the facebook.com site to be blocked and then I can't access it on any PC on the network. However the Facebook app on my iPad still let's me connect (on local wireless-n network). Is there a way to set OpenDNS to block this iPad app also?

    You're most likely not using OpenDNS with that iPad. Visit http://welcome.opendns.com/ with it.

    Where did you configure the OpenDNS resolver addresses, on the router, or on the devices? If on the router, it should take effect also on the iPad, else you had to configure the iPad too.

    OpenDNS is configured on the router not on the iPad itself.
    What I would like is to be able to lock-down the network using OpenDNS at router level so that whatever mobile device connected into it was subject to "house rules".
    It may not be possible to set up OpenDNS on the iPad itself - for instance I may not own the iPad (or other mobile device)... Domain name blocking on its own seems to be bypassed by the Apple "app".

    Depending on your router - you should be able to identify the ipad in your router settings via it's MAC address, and then limited or screen the ipad's access to various domains (such as facebook.com, or certain keywords, etc).

    Did you visit http://welcome.opendns.com/ with the iPad you tested with? What was the outcome?

    If you get an "Oops!", you had to check the iPad if it has manually alternative DNS server addresses configured, i.e. not the router's IP address and not the OpenDNS resolver addresses.

    Also, it could well be that an app disregards the iOS settings and plays with DNS on its own.

    Why not block DNS (TCP port 53) on your router?

    Your network clients should be asking the router for DNS lookups, they shouldn't be carrying out their own dns queries directly.

    That way, any devices that are attempting to use their "own" DNS will be prevented from doing so.

    On my Linksys Router running Tomato, I could successfully block facebook on all machines using the domain names
    .facebook$
    .fbcdn.net$

    however the Android and iPad apps on tablets and phones could still access. From tracking the router logs the apps were accessing via SSL (port 443) but only by IP Address, not FQDN.

    Adding these IP Addresses has stopped the Apps as well:

    To 66.220.144.0-66.220.159.255, any protocol
    To 69.63.176.0-69.63.191.255, any protocol
    To 204.15.20.0-204.15.23.255, any protocol
    To 69.171.224.0-69.171.255.255, any protocol
