That feature was taken out a while back (when reducing the memory requirements). Too bad, but I guess it was worth it. I'm hoping it will be back when more of the memory optimization work is complete.
Anyway, the terse answer is you can't (at least, not easily).
A possible workaround might be to use the IP's you can see in the Search results under the Location column, and use the Direct Connect search. AFAIK, you can't get the list of multiple IP's from the Downloads panel, even with extended tooltips turned on.
Still, Direct Connects are like Browse host, with all the reasons they don't work too
