you need to use the map command, The ping command in this app which gives info like dest,sent , packet loss etc are all based on the host field , which is a ip address.
Try this in your network toolkit app
index=abc | stats values(host) as host | mvexpand host | map search="| ping host=$host$ count=1 | eval dest=if(isnull(dest),host,dest) | fields dest sent received packet_loss min_ping avg_ping max_ping jitter | eval row="Value" | transpose column_name=Data header_field=row"
NOTE : The command /app itself is a bit slow, strongly suggest to limit initial host set to only 3 ips at first
See the output and then decide how to proceed further, all I am doing above is passing each host value from your index into the ping command, it works like a for loop.
