IPv4 became the main protocol governing data packet transmissions in 1981. TCP sits atop IP and addresses these shortcomings through mechanisms such as data integrity checking.

IPv4 is a connectionless protocol operating on a best-effort delivery model, which means it does not guarantee delivery nor can it avoid duplicates. What are the major differences between IPv4 and IPv6? Let’s find out. The two versions currently coexist, and IPv6 will take over once the IPv4 addresses run out. IPv4 and IPv6 stand for Internet Protocol version 4 and version 6, respectively. Soon after, it became the primary standard for packet-switching networks like the internet.

It became the computer networking standard for the US military in 1982. TCP/IP was developed by the Defense Advanced Research Projects Agency (DARPA), a US federal agency under the Department of Defense. TCP, Transmission Control Protocol, governs the transport layer while IP is concerned with the network layer. IP is the other half of TCP/IP or the so-called Internet Protocol Suite.

Data packets with the IP information of their points of origin and their destinations travel on the internet, with routers helping to direct them down the correct path. They direct packets to their intended destinations. IP controls all internet traffic. IP addresses operate in the same way as street addresses laid out on a map. Whenever you open a website on your browser, a data packet with your IP address is sent to the web server’s own IP address, after which the website is then served over the internet back to your device. The Internet Protocol, or IP, is the set of rules that makes it possible for our computers and other communication devices to connect to each other over the internet.
