This is very good news, except it sounds like you still can’t see the performance of individual parked domains in the Google Search network; only the content network:
Parked domains information in Placement Performance Reports
If you’ve run a Placement Performance report recently, you know that you can see the individual sites in our content network that displayed your ads. Including the “Special Category” column will introduce line items for parked domains, which are sites in our network utilizing AdSense for Domains. AdSense for Domains allows domain registrars to show relevant ads, rather than empty space, on parked pages.
You’ll now be able to see the specific AdSense for Domains sites that your ads have appeared on, rather than seeing statistics summarized in one consolidated entry. Armed with this information, you can exclude sites that don’t convert well to improve your overall performance on the content network, or you can exclude the parked domains category to prevent your ads from appearing on any AdSense for Domains site in the Google Network.
