Welcome to WebmasterWorld Guest from 188.8.131.52
The Hostnames report under, "Visitors" --> "Network Properties" --> "Hostnames" isn't showing the domains of users visiting the site, it's showing the domains of our site!
The "About This Report" description says: "From which hosts are people visiting your site? Hostnames sometimes provide insight into organizations that are interested in what you offer." But I've been going back and forth with their support over this issue, and they insist they see no issue, and are trying to convince me I'm using it wrong.
For those using GA, what do YOU see in this report within the new UI?
