Now some of my routers have more than 30 IPs because they have many PPP/tunnel interface.
The Dude will auto add first 20 IPs for each router on the scan, and can manually add IPs up to 30 now, but no more, this (maybe) cause my router to have multiple duplicated on the map.

I know too many IPs may couse long height window, maybe also change the IPs display style to a list with slider.
