A Short IPv6 Guide for Home IPv4 Admins

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:

Concept 1

Linuxルーターを使ってる人向けのニッチなものだけど、情報として残しておく。

Using test collections in xUnit.net v2

Test collections are the test grouping mechanism in xUnit.net v2. They serve two purposes:

  1. They delineate the "parallelism" boundary; that is, tests in the same collection will not be run in parallel against each other;
  2. They offer collection-wide fixtures through the use of ICollectionFixture<TFixtureType>.

The simplest way to use test collections is simply by name. Put two classes into the same named collection, and they can derive benefit #1 above:

[Collection("MyCollection")]
public class TestClass1
