    It means exactly what it says.  As for every entry in your domain stats: There is some networking application in your network which raises DNS lookups for domain name "local". 
    You can do this willingly too to blow up your stats with this if you like:  nslookup local.

    It seems there are attempts to resolve a network name internal to your network, or a pure DNS suffix defined in your router or computer settings.  For example, this could be a useless attempt to find wpad.dat as Windows systems tend to do...

    Not sure I understand it fully...sorry...

    It means that the website looks at a data on my laptop ? is it normal or not ?

    It means that something on your own local network is looking for something else on your local network, and is trying to use DNS lookups to find it. OpenDNS cannot resolve the lookup since it has no insight into your local network, but it still logs the attempted lookup.

    It generally means that a piece of software on a device on your local network is doing the lookup, rather than anything related to a web browser or website.

    ok, Thanks for the information.

    Does it means that I have a "malicious" software on my laptop for example ?

    Or can I forget this issue ?

    Without knowing what software on your system is doing what I can't say for sure what it is or what it's doing. All that I can tell you for certain is that something is attempting to use DNS to lookup local resources.

    If you are concerned about malware you need to be running antivirus and antimalware software on your computer.

    If you don't have the technical skills or experience to recognize when your computer is infected and are concerned that it is you should contact someone with the expertise to determine that for you.

    The current pc are a Ipad, Iphones, macbook and an Samsung android.

     

    What are the typical software that use the DNS in order to have a look at local ressources ? could it be instagram or facebook with picture uploading for example ?

    From your machine park the most likely device is your MacBook being in charge for this kind of name resolution.  Smartphones and the likes do not tend to use local resources.

    "What are the typical software that use the DNS in order to have a look at local ressources ?"

    This can be any networking software, especially software dealing with local resources on your network.

    "could it be instagram or facebook with picture uploading for example ?"

    These aren't local software, but online services, so no.  However, if you're using dedicated "apps" talking to such services, it could be one of those apps too trying to lookup local resources.

    Ok. Thanks!!!!

    I supoose it was the macbook with pictures uploading and/ the instagram/ Facebook app of our daughter on her Samsung android with pictures uploading.

    The kind of information you're asking for is well beyond the scope of this forum. It touches on some of the basics of networking and computing. There are literally tends of thousands, or more, pieces of software or apps that could be trying to access local resources in this way. The most common would be anything that is trying to access a printer or networked scanner, or some sort of "file explorer" application, such as would be used in opening files locally, or uploading them to some internet based service.

    I do agree with robblitz that the MacBook is most likely the source of most, if not all, of this traffic.

    Could It be my ipad when i share my internet from my iPhone without using the wi-fi that uses opendns?

    If you aren't using OpenDNS then OpenDNS won't receive any DNS requests to log. If the iPhone is not connected to the router, or otherwise configured to use OpenDNS, then it doesn't matter what devices or software you are using, the traffic will never be sent to OpenDNS in the first place

    Thanks! It makes sense since I'm not letting the traffic pass via opendns. But still I find i strange that somedays I get a lot of local in the trafficstats and somedays I don't get anything.

    "I'm not letting the traffic pass via opendns."

    In this case your dynamic IP address may be sometimes registered with another OpenDNS user's account, and you are catching someone else's DNS traffic, else your stats would always be empty. 
    The following command will show more details:  nslookup -type=txt debug.opendns.com.  208.67.222.222 
    If the "originid" is not zero, your current IP address from "source" is registered and possibly being used somewhere at OpenDNS.

    Or you are in error, and some of your devices has the OpenDNS resolver addresses configured, maybe beside other addresses, so that some DNS traffic still goes to OpenDNS. 
    Visit http://welcome.opendns.com/ on every device to find out, or check all DNS server addresses being configured on each device.

    Or it is a mixture of the two scenarios above.
