In an IP address like 64.26.209.103:5060, the port number is the number after the
colon ‘:’. For this example, 5060 is the specified port.
Port numbers are required so that a computer or device can support multiple appli-
cations or streams of simultaneous data communication. Each stream or application
uses a unique port number. You can think of it like mailing a letter to friend in an
apartment building at a specific address. You need to specify the apartment number
as well as the building address, so that the mail can reach the proper final destina-
tion.
