In a standard IP header, there is no place to indicate which port the data packet should go to. IP headers only indicate the destination IP address, not the port number at that IP address. Usually, the inability to indicate the port at the network layer has no impact on networking ...
At this stage the router receives the response from the destination server and performs reverse PAT on it. When a response is received, the router translates the source’s public IP address and port number back into the original source computer’s private IP address and port number before sendi...
A port in computer networking is how a computer can use a single physical network connection to handle many incoming and outgoing requests by assigning aport numberto each. The numbers go from 0 to 65535, which is a 16-bitnumber. Some of these port numbers are specifically defined and always...
A network port is a communication endpoint in computer networking, crucial for establishing network connections and facilitating data exchange between devices. Each port is identified by a unique number, ranging from 0 to 65535, allowing the network to distinguish between different types of network tra...

A comprehensive guide to tunneling in networking, including how it works, types of tunneling, pros and cons, and tunneling attacks.
Networking diagram of PPPoE access The process in which a PPPoE user goes online has two stages: the discovery stage and the PPP session stage. In the discovery stage, a PPPoE server is selected, and the ID of the session to be established is determined. The PPP session stage is the stan...
Before we delve into more complex networking topics, it’s important to understand fundamental networking components, including: IP address:An IP address is the unique number assigned to every network device in an Internet Protocol (IP) network; each IP address identifies the device’s host network...
When a device sends data to a switch, the switch examines the destination MAC address and selectively forwards the data only to the device with that specific MAC address. Conclusion In summary, understanding what is a hub is important as it allows us to recognize their uses in different ...
Access link: connects network nodes and compute nodes. A node's port, when connected to an access link, is called an access port. Comparison between adaptive routing networking and topology In the dragonfly topology, the sum of bandwidths between each network node and other network nodes in ...
