IPv6 is the next-generation IP address standard designed to enhance and eventually replace IPv4.
What is IPv6 used for?
IPv6 is the most recent version of the Internet Protocol, which identifies machines on the Internet and allows them to be located. Each device that connects to the Internet is allocated its unique IP address for internet communication to work. In that sense, it’s similar to knowing the street addresses and zip codes required to mail a letter.
Should I have IPv6 on or off?
Some users deactivate IPv6 on routers or devices because they do not use IPv6-enabled applications or services. When troubleshooting network issues, it is often usual to disable IPv6. Most services have switched to the new IPv6 protocol, although some still use IPv4. Most operating systems, including Windows, macOS, and Linux, support and activate IPv6.
Should I use IPv4 or IPv6?
IPv6 is more advanced and has more functionality than IPv4. It is capable of providing an endless number of addresses. It is replacing IPv4 to handle the increasing number of networks worldwide and to assist in solving the problem of IP address exhaustion. The protocol you use may be determined by factors such as your device and the applications and services you use.
