A Short IPv6 Guide for Home IPv4 Admins

This guide is for homelab admins who understand IPv4s well but find setting up IPv6 hard or annoying because things work differently. In some ways, managing an IPv6 network can be simpler than IPv4, one just needs to learn some new concepts and discard some old ones.

Let’s begin.

First of all, there are some concepts that one must unlearn from ipv4:

Just F-ing Ping

Because sometimes you just want to f-ing ping!

Modern browsers, believing they are being clever, hide the protocol in the URL bar.

However, even if you only select the hostname, when you paste that URL into your terminal, you will encounter the following:

(* Extended dual regular expressions (Alexander Okhotin: The dual of concatenation).

   The dual of constants is their complement.
   The dual of the union is the intersection defined as DualUnion (x, y) = (Comp (Union (Comp x) (Comp y))).
   The dual of the concatenation is defined analogously as DualConcat (x, y) = (Comp (Concat (Comp x) (Comp y))).
   Other dual operations are constructed out of these duals in the customary way.
   The duals are essentially just the "upside-down" versions of the operations.

   The derivatives of the dual operations are constructed out of the duals in the customary way.
