| | What is PING? (Site not responding. Last check: 2007-11-01) |
 | | PING can provide round-trip times between the local host running the PING and the target host the local host is pinging; however, these round trip times are often deceiving and cannot be relied upon as the nature of IP networks has altered considerably since this tool was created. |
 | | Ping utilizes raw ICMP sockets to send packets to a remote host, calculates the difference in timeticks between transmission of an ICMP echo and receipt of the ICMP echo reply packet and produces printed, human-readable results of these measurements in milliseconds. |
 | | Ping was written on a BSD platform, not for a mixed network of routers, servers, switches and other gear, each with its own strategy for handling ICMP. |
