How to enable IPv6 on Ubuntu 20.04

Ubuntu 20.04 generally has IPv6 enabled by default. To confirm or manually enable it, you can check your network configuration files or use `sysctl` commands. For persistent changes, edit `/etc/sysctl.conf` and uncomment or add lines like `net.ipv6.conf.all.disable_ipv6 = 0` and `net.ipv6.conf.default.disable_ipv6 = 0`. After saving, apply changes with `sudo sysctl -p`. NetworkManager, commonly used on Ubuntu, also manages IPv6 settings through its GUI or `nmcli` for dynamic configurations. If your router and ISP support IPv6, your system should automatically obtain an IPv6 address via SLAAC or DHCPv6.
