The Internet Protocol (IP) is the network layer communications protocol in the Internet protocol suite that relays datagrams across network boundaries. Its enables internetworking through its routing function, and sets up the Internet.<\/p>\n\n\n\n

The first major version of IP, Internet Protocol Version 4 (IPv4), is the dominant protocol of the Internet. Its successor is Internet Protocol Version 6 (IPv6), which has been in increasing deployment on the public Internet since c. 2006<\/p>\n\n\n\n

What is IPv4?<\/h2>\n\n\n\n

IPv4 or Internet Protocol version 4 is the underlying technology that connects our devices to the web. Every time our devices access the Internet, it is assigned a unique, numerical label such as 192.0.2.1. A data packet must be transferred across the network containing the IP addresses of both devices, to send data from one computer to another through the web.<\/p>\n\n\n\n

What is IPv6?<\/h2>\n\n\n\n

IPv6 is the next generation Internet Protocol (IP) address standard, which was intended to supplement by replacing IPv4. It is the protocol which many Internet services still use today. Every computer, mobile phone, home automation component, IoT sensor and any other device connected to the Internet needs a numerical IP address to communicate between other devices. IPv4, the original IP address scheme, which is running out of addresses because to its widespread usage from the proliferation of uncountable connected devices.<\/p>\n\n\n\n
