    If you have blocked all available categories. Skype should be blocked for you.  If not, post the complete plain text output of the following commands:

    nslookup -type=txt debug.opendns.com.
    nslookup skype.com.
    nslookup www.skype.com.
    nslookup skype.net.
    nslookup www.skype.net.

    You open a command prompt or terminal window and enter (e.g. copy & paste) those commands. Then you copy & paste the text output to here.  We may be able to see why skype can still be accessed.

    Hi. shall i open the terminal window in windows, or in the router and will this block skype for all times or will it block it just when i use the parental controll?

    The command outputs are for diagnostic purposes only.  I want to see if and how skype is not blocked for you.

    The commands will not block skype at all.

    You open a command prompt window in Windows.

    From the output of the first command I see that you're using Netgear LPC with device ID 000043553b691242.  You're using the Frankfurt OpenDNS location.  But your IP address 46.9.173.146 is also registered with a normal OpenDNS network ID 20053413.

    And yes, Skype is not blocked with your settings, their real IP addresses are returned, most likely because you may manage both, a normal OpenDNS network at https://dashboard.opendns.com/settings/ and an LPC network at https://netgear.opendns.com/
    If you do not maintain a network at the normal OpenDNS dashboard, then another OpenDNS user has registered your IP address 46.9.173.146 with an OpenDNS network.

    That said, visit https://dashboard.opendns.com/settings/ to delete any network you may have configured there.  If there is no network, open a support ticket to get your IP address information removed from the other OpenDNS network ID 20053413.

    Normal OpenDNS and Netgear LPC are not compatible.  You can use either the one or the other, but currently you're using both in some way.

    Yes, when your IP address information will have been removed, you should be able to use Netgear LPC.

    Hey, I thought maybe you would know the answer from the other "helpline" you suggested. There was no IP address that was registered there, so they tried something different. Here's what they came up with:

    Thank you for the diagnostics. skype.com is not blocked in the first diagnostic and is in the second which indicates that OpenDNS is working correctly. It appears that since Skype is already installed on the computer blocking its domains will not fully block access since it uses IPs dynamically to maintain a connection.

    I have found a few articles related to completely blocking Skype when it is already installed but they require blocking more than domains:

    http://blog.imfirewall.us/How+To+Block+Skype.aspx
    https://supportforums.cisco.com/thread/2129294
    http://sg.answers.yahoo.com/question/index?qid=20100810010101AA3hUkZ

    Normally, I would suggest uninstalling Skype from these machines because blocking the domains skype.comskype.net and skypeassets.com would prevent the download/access to Skype, but since you don't want to completely block Skype this method won't do you any good. Since the Skype client doesn't use domains to communicate it can't be temporarily unblocked using OpenDNS.

     

    Ok, thanks for the help, and have a nice day

    with regards,
    Thomas

    If you have a dynamic IP address (most likely), your IP address may have changed and is no longer registered with OpenDNS.  You can always check this with 

            nslookup -type=txt debug.opendns.com.

    If there is "id 0", then it's not registered, else it is.

    This is why the OpenDNS guy said that your IP address is not registered.
