This protocol is usually TCP, UDP, or ICMP. If this protocol is TCP or UDP, there is a source port and a destination port. Most often the source port is a random port and the destination port is a well-known port number. For example, the destination port for HTTP is 80 and the destination port forDNS is 53.
