![]() ![]() Dynamic IP addresses are assigned by your ISP when you connect and can change over time. Your home Internet connection may be a static IP that is tied to your router. A static IP address will not change between network connections. Here is the other big difference in the type of IP address that you might be using when you connect to the Internet. Though not directly compatible, the two protocols can operate together. The main reason that IPv6 is around is that IPv4 cannot supply enough IP addresses for all of the world’s network-attached devices. Addresses are expressed in hexadecimal format like this: There is a limit of 4,294,967,296 unique addresses that can be constructed using the IPv4 protocol.Īn IPv6 address uses 128 bits which exponentially increases the number of unique addresses it can create to 340,282,366,920,938,463,463,374,607,431, 768,211,456. You are probably familiar with IP addresses that look like this: These two versions of IP are currently used for the purposes of location addressing and identification.Īn IPv4 address is comprised of 32 bits and is expressed in decimal format. Here are the main distinguishing characteristics that differentiate IP addresses. IP addresses come in a variety of flavors. The address ensures that the data is sent to the correct destination. IP handles the address of each data packet.It also reassembles the packets when their destination is reached. TCP is the element that breaks up a file or transmission into packets to be sent over the Internet.So the acronym TCP/IP comes from the protocols used in two layers. This layer is responsible for standardizing how applications exchange data. The application layer is made up of many protocols including File Transfer Protocol (FTP), Simple Mail Transfer Protocol (SMTP), and HyperText Transfer Protocol (HTTP).Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are two of the possible protocols used in this layer. It controls the communication between hosts. The Internet Protocol (IP) and Internet Control Message Protocol (ICMP) are used in this layer. The network layer is used to connect networks and transport data packets across network boundaries.Ethernet is an example of a protocol that operates in the datalink layer. In network terms, a link connects hosts or nodes on a network. The datalink layer is made up of protocols and methods that only work on a link.There are four layers and each has its own set of protocols. Let’s take a little dive into the functionality that TCP/IP provides. ![]() They are two distinct entities but are often used together, and the term TCP/IP is the de-facto standard for describing the protocols. The majority of computer networks, including the Internet, employ Transmission Control Protocol/Internet Protocol (TCP/IP) to enable communication between network-attached devices and computers. ![]()
