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:

Picking a Java Runtime

Use Java 17-22. There isn't much difference between versions from 17 to 22. Java 23+ is not recommended because of Generational ZGC, see below.

Java runtimes from Adoptium, Oracle, Azul and so on are basically identical. If you don't know what to pick, I recommend the latest Adoptium Java 21 JDK: https://adoptium.net/

Some notable exceptions:

• Oracle GraalVM features a more aggressive Java compiler. It seems to be worse at the start of the session, but then becomes faster than Adoptium; see the GraalVM section.

Basic JavaScript MVC Implementation

Despite being derived from classical MVC pattern JavaScript and the environment it runs in makes Javascript MVC implementation have its own twists. Lets see how typical web MVC functions and then dive into simple, concrete JavaScript MVC implementation.

How Web MVC typically works

Typical server-side MVC implementation has one MVC stack layered behind the singe point of entry. This single point of entry means that all HTTP requests, e.g. http://www.example.com or http://www.example.com/whichever-page/ etc., are routed, by a server configuration, through one point or, to be bold, one file, e.g. index.php.

At that point, there would be an implementation of Front Controller pattern which analyzes HTTP request (URI at first place) and based on it decides which class (Controller) and its method (Action) are to be invoked as a response to the request (method is name for function and member is name for a variable when part of the class/object).
