The following grammar is based on this EBNF specifications for EBNF meta-grammar:

ebnf            ::= [ global-desc ] { local-desc | rule | comment }

local-desc	::= '{' ? { any-character } ? '}'

global-desc	:: "{{" ? { any-character } ? "}}"

rule ::= identifier '::=' expression [ '.' ]

A Short IPv6 Guide for Home IPv4 Admins

Let’s begin.

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

Concept 1

Adapting the twelve-factor methodology for "Qubes-native" multi-VM applications: a preliminary sketch[^1]

Introduction

Virtualization is the conceptual technology on which modern services (server applications) are built. Whether an application happens to run on a fully- or para-virtualized VM[^2] or is containerized—or even runs on a “bare-metal” physical server after all—most modern services are designed in isolated, replicated, disposable components on commodity hardware.[^3] The [“twelve-factor methodology”][wiggins] (2011) is an influential articulation of the principles
