This pull request improves the IPv6 networking documentation by adding a clear warning that the IPv6 prefix
2001:db8::/64is reserved strictly for documentation and example purposes.The update helps prevent users from mistakenly using reserved IPv6 ranges in real-world environments, which could lead to misconfiguration or unexpected network behavior. It also guides users to replace the example prefix with a valid IPv6 subnet allocated to their network.
This change enhances clarity, accuracy, and usability of the documentation for developers and system administrators.
