IPv6 (Internet Protocol version 6) is a protocol for internet addressing and routing that provides an enormous number of unique IP addresses, compared to the limited number of IPv4 addresses. IPv6 is designed to replace the current standard, IPv4, which has been in use since the early days of the internet.
IPv6 addresses are 128-bit binary numbers and can be written in hexadecimal notation. The length of an IPv6 address allows for trillions of unique IP addresses, which will support future growth and development of the internet.
In addition to providing more IP addresses, IPv6 also offers other benefits such as improved security, simplified network configuration, and better support for mobile devices. However, adoption of IPv6 has been slow due to various technical challenges and the need for infrastructure upgrades.
