Block whole internet access

    No, OpenDNS can't do this. This feature wouldn't make sense. DNS is only meaningful when an internet connection is up.

    So, what would one do to cut the access to the internet? Right! Unplug that cable to the router, and/or deactivate the WLAN adapter. Think about that software updates/patches are not possible either anymore. So, occasional you want to establish internet access to keep your systems current.

    You should be able to block specific computers through your router (via IP or MAC) setup.

    But rotblitz raises a good point about updates/patches (which would include security fixes, AV sigs, etc), and in some instances, program license authentication.

    You could also allow it on the network (to print or stream itunes or UPNP Devices, Or to access a server only) using a feature of advanced routers called VLAN.  Create a Virtual Local Area Network for inside only and a VLAN for inside and outside. This would allow full access to anything inside the network but prevent outside access.  Or if you can put a bad DNS server on that computer.  send it to loopback 127.0.0.0 or broadcast 255.255.255.255 either way it would not beable to surf the web because DNS would be broken. When you need to update or register software just change the DNS back, or make a config in your etc/Hosts file for those static services you want.  update.windows.com etc.   we do this for warehouse computers, or store kiosk models.

    I would like to block all internet sites at given times, i.e. at 10:30 I'd like my kids access to go down, but allow my own access to continue. Any suggestions?

    Hmm, it seems you didn't read the answers above.

    Thank you, but I did read the answers. The answer stated that it wouldn't make sense, but that is not a viable answer to my question.   I want to have internet access to the devices, I just want to stop all traffic on those devices during certain periods of time.

    So, nashuadatasolutions thank you for your suggestions, but creating a VLAN is out of my scope, is there an easier way through OpenDNS or some other canned program to acheive my goal?

    @lisa... Tell your kids "No 'net after 10:30". Take away their devices if they ignore you.

    You would have to have a look at your router. Many have a variety of features like disabling internet at particular times. As noted previously, there is no way to do this with OpenDNS, as you are *already connected to the internet to use OpenDNS at all*.

    "I just want to stop all traffic on those devices during certain periods of time."

    This is a router or local function, not a function of any external service like OpenDNS.  And yes, you can do it also with a DNS method while switching the locally configured valid DNS service on those devices to an invalid DNS service, e.g. 0.0.0.0.  This looks like no internet connection then.  But still a local function, unrelated to OpenDNS.

    I agree with Rotblitz in that this is a local function.  That is the reason I bought this super duper router, with the promise of better access control.  My previous router allowed control by time to each mac address, so I could deny access to the network to specific users during given periods, addressing the the problem that Sews1 poses.  Looks like I have to restore my old router.
