It's main purpose is to replace and complement the ping command, adding certain enhancements as fragmentation; send and receive spoofed packets; send many ICMP information types (echo as the old ping, address mask, timestamp, and router discovery) and errors (redirect, unreach, and time exceeded); and send monster packets. It also supports loose and strict source routing and record routing.
