Blocked domain report question

    No version of OpenDNS is not useful for monitoring internet, especially web browser, usage anywhere on your network. It is a very good tool for controlling access via DNS lookups, but since it only knows about DNS lookups it can't can't give an accurate picture of usage.

    OpenDNS Home (the free version) does not provide time stamps for individual lookup requests that it receives. It only provides time delayed reports of DNS activity, with full reporting for the previous day and older.

    Also, it does not, and cannot, provide any information about which device made an individual since it does not receive that information in the first place. It tells you about the total DNS traffic received from your network.

    The report tells you nothing about sites visited. It contains information about DNS requests that OpenDNS has received. Those can come from web browsing, email activity (including resolution of DNS requests from HTML formatted emails), software updates, FTP traffic, and any other network activity that generates a DNS request. That also includes all of the scenarios you mention, though all of those scenarios are just web browser activity. It provides information on all requests, blocked or not, though you have various filtering and sorting options for how you view the information. It does not provide any information for DNS requests that are handled internally on your network via caches or any sort of local DNS server, which very well could be running on your router as well.

    The blocked report provides you information about what it says, DNS requests that were blocked according to the categories and domains that you've blocked. Just like any DNS request it will be logged, and if you are looking at the blocked domains then it will be there as well.

    OpenDNS being a DNS based service, knows nothing about websites, webpages, URL's, content, or anything else. It doesn't know if that activity came from a person browsing to a website, ads or scripts on a page someone has visited, or if that activity came from your email software, software updates or anything else. It literally only knows that something from your network made a DNS request, and processes and logs that request.
