Please list the URL for the main site on which you'll run ads. This is for application purposes only — you'll have the chance to publish ads on other pages and/or sites as well.
Does this mean I can add the same code to any of my sites?
Google does have something that they're not telling us about which allows them to identify sites and owners. I run four sites all on different IPs (same block) but they all show up as being related to each other when I do a "related sites" search.
