Great question. You could adjust the formulas but I find it easier to highlight the full report (after it is populated with your data) then copy it and paste "values only" this way none of the formulas break. Then go into the navigation of google sheets and select "Data" then "Filter". You will now have filtering options on all of the headings. Then you can simple select your website and uncheck "Yes" so you only see the domains that do not link to you. Give that a shot and let me know if it works for you.
Now the ad servers don’t create this table themselves, they license it from another company like MaxMind or DigitalEnvoy, whose primary business is geolocation data. This is no enviable task; IP addresses themselves don’t necessarily have an obvious pattern in the way they are assigned like a telephone area code would. It’s a bit like solving a mystery, and the geolocation companies use a variety of methods to approach the problem. /injects>
