IPv6 stands for “Internet Protocol Version 6”. It solves a number of problems that IPv4 has, such as the limited number of available addresses in IPv4. IPv6 address is 128 bits and IPv4 is only 32 bits.
1. Should I use it?
It depends on the sites you want to visit, or from where they are visited. If they run on IPv6, you can reach them when your computers run on IPv6 too. But if they only run on IPv4, your computer must also run on IPv4. If you want to experience a website under IPv6, Hurricane Electric IPv6 Tunnel Broker would help.
If you don’t need IPv6, it may not be good to install and enable it on your computer. It’s because it will direct your computer to reach a non-existent IPv6 site whenever you try to reach a IPv4 site. This can result in needless timeout and “destination not found” messages. Please consult your IT support before using it.
