Описание (Description)
ping uses the ICMP protocol's mandatory ECHO_REQUEST datagram to
elicit an ICMP ECHO_RESPONSE from a host or gateway. ECHO_REQUEST
datagrams ('pings') have an IP and ICMP header, followed by a
struct timeval and then an arbitrary number of 'pad' bytes used
to fill out the packet.
ping works with both IPv4 and IPv6. Using only one of them
explicitly can be enforced by specifying -4 or -6.
ping can also send IPv6 Node Information Queries (RFC4620).
Intermediate hops may not be allowed, because IPv6 source routing
was deprecated (RFC5095).
