I started to learn about ping and had some questions.
>> Ping ipadrr
So when we ping on some IP address, we send an ICMP message to the IP address. but how does the NIC on the receiver side knows which application or port number to pass the ICMP message.

Sorry i just started reading about ICMP and ping and TCP. and i am just trying to see how this works. I will really appreciate any help.
