IP filter
 

Could there be some color coding or such that highlights an item in the search results if the IP of the host that owns the file cannot be connected to, for example IPs like 192.168.1.x or 10.x.x.x (private ips) or possibly a filter to clean these search results out if a connection cannot be made.

you can already filter out hosts in options/filters/hosts

all you have to do is filter 192.168.*.* or whatever to filter any i.p starting in that number . using star to mean all numbers

and yes the it could be better
