Dec 17, 2018 · It is commonly known as internet protocol suite. The TCP/IP protocol consists of four layers such as link layer, network layer, transport layer, and application layer. Each layer adds addresses to the protocol stack as a physical address, logical address, port address, and application-specific address.
When a data frame is received, the switch will store the mapping relationship between the source MAC address of the data frame and the corresponding port number in the MAC address table for subsequent data forwarding. However, in this line of data forwarding, the target MAC address is used, and the MAC address table is queried. How Do IP Addresses Work? An IP address uniquely identifies a device on a network. You’ve seen these addresses before; they look something like 192.168.1.34. An IP address is always a set of four numbers like that. Each number can range from 0 to 255. So, the full IP addressing range goes from 0.0.0.0 to 255.255.255.255. What Is the Difference between a Socket and a Port? The main differences between a socket and a port are function and location. A port is always on a computer and acts like a docking station. It has its own location and is stationary. A socket does not have a number and moves around, connecting computers and then severing when the connection is finished.
An IP address is your devices address on the network. Think of a port as a location in that address. Think of it as a Post Office. The office has a single address that everything goes to, yet it's full of Post office boxes.
In TCP/IP, a port is software based end point in an Operating system. Each port is assigned a number. It is called port number. A port number can be 0 to 65535. There are UDP and TCP port numbers in the same range. ===== Common Protocol Numbers . Protocol Number. Internet Control Message Protocol (ICMP) 1. Transmission Control Protocol (TCP) 6 Mar 12, 2014 · The idea is that you can add a specification in the IP address itself as to the number of significant bits that make up the routing or networking portion. For example, we could express the idea that the IP address 192.168.0.15 is associated with the netmask 255.255.255.0 by using the CIDR notation of 192.168.0.15/24 .

Oct 08, 2017 Discuss the different types of addresses used in the TCP A port number is part of the addressing information used to identify the senders and receivers of messages. Port numbers are most commonly used with TCP/IP connections. These port numbers allow different applications on the same computer to share network resources simultaneously. Difference between WAN IP Address and WAN Static I Difference between WAN IP Address and WAN Static IP Address? when i look at my cable modem status page i see the below image. some octets X'ed for privacy. why is the modem assigned 2 separate ip's? one is my static addr (173.) and other (73.) some random wan address.
