After I get the beta released I plan on reworking the ranking.
I think you can get what you're after by using the "full listing" search option.
By default it shows a lot of noise. But you can modify the search to show only what you're after.
It's a little tricky. First, I sort by upload. Then tell it to only show tables that have over 45K results by modifying the URL string in the browser. Specifically I'm telling it 45,100 results to pull up the more popular hosts.
The tables in the database that tool is searching are pruned daily to a max of 45K results, for speed. So a host that has over 45,100 results shows that there's more recent activity on that host.
Depending on when you query this, it may be different. The pruning and caching of the count are all done automatically on a schedule by the system.

Once I shift my focus back to databasing I'll work to make that more simple and intuitive.
One of these days I'll make all the data available and easier to digest.
