Ping a specific port
This option is used with the -U option. The default base port number is 33434. The ping utility starts setting the destination port number of UDP packets to this base and increments it by one at each probe.
Which port is used by ping utility?
What Port Does Ping Use? Remember that a ping test uses ICMP, so there are no real ports being used. ICMP basically roofs, or sits on top of, the IP address. Therefore it is not a layer four protocol.
What is the port number of ping?
ICMP doesn't use port numbers, so there is no port for ping. Some people may use the phrase "ping a port" informally meaning to open a TCP connection to that port and see if a response is received, but practically speaking, there is no ping port.
