That's like saying, Sharks dont eat people. Some sharks do, some sharks don't. If I'm not mistaking, there are several kinds of Pings. There's an UDP Echo port (port 7) that can be used for pinging, plain Ping is over ICMP, etc. I think Net::Ping supports 3 types of pinging, being ICMP, UDP and TCP pings. But there are ofcourse dozens of other ways to detect if a host is online.
