How to Disable IPv6 in UFW Firewall on Linux Ubuntu

How to Disable IPv6 in UFW Firewall on Linux Ubuntu | Debian

Internet Protocol version 6 (IPv6) is the most recent version of the Internet Protocol (IP), the communications protocol that provides an identification and location system for computers on networks and routes traffic across the Internet. It was developed in 1998 to replace the IPv4 protocol.

IPv6 aims to improve security and performance, while also making sure we don’t run out of addresses. It assigns unique addresses globally to every device, storing them in 128-bits, compared to just 32-bits used by IPv4.

Although the goal is for IPv4 to be replaced by IPv6, there is still a long way to go. Less than 30% of the sites on the Internet makes IPv6 connectivity available to users (tracked by Google here). IPv6 can also cause problems with some applications at time.
