- Latest request time: This is the time, when the request packet was seen. If more than one packet has been seen, the latest timestamp is shown.
- Ping sent to: The IP adress that receives the ICMP request and (usually) sends the ICMP reply.
- Latest reply time: This is the time, when the reply packet was seen. If more than one packet has been seen, the latest timestamp is shown.
- Number of ping requests: This is the total amount of ping requests sended from the requesting IP to the receiving IP adress.
- Number of ping replies: This is the total amount of ping replies sended from the IP, that received a request, to the requesting IP adress.
