TCP/IPnetworks use port 3360. The connection-oriented protocol TCP demands handshaking to set up end-to-end communications. Upon establishing the connection, user data is transferred bidirectionally over the connection. What is my IP address and port number? The easiest way to find arouter's publ...
TCP and UDP headers have a section for indicating port numbers. Network layer protocols — for instance, the Internet Protocol (IP)— are unaware of what port is in use in a given network connection. In a standard IP header, there is no place to indicate which port the data packet ...
A port number is a unique identifier used to specify a particular process or service on a host, such as a computer or server. When data travels over a network, it needs to know which application on the receiving device should handle that data. Each network-connected device have a port ass...

SMTP has an asymmetrical mechanism that allows many clients to interact with one server, using theTCP/IPsuite. Email protocolsare sets of rules designed to organize the exchange of information between email clients (MUA) and email servers. The Simple Mail Transfer Protocol is dedicated to sending...
