Guess, your question has been asked and answered dozens of times here already. Again...
OpenDNS as DNS service does not know what web sites are being visited. It only knows what domain names are being looked up and from what public source IP address. Your network internals like devices and users are (fortunately) not visible to the public internet, so cannot be logged by OpenDNS.
Some OpenDNS Enterprise solutions with AD integration support logging the details you are looking for:

Alternatively, if your router supports logging, you may be able to log the details you want to see.
