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:

Things I believe

This is a collection of the things I believe about software development. I have worked for years building backend and data processing systems, so read the below within that context.

Agree? Disagree? Feel free to let me know at @JanStette. See also my blog at www.janvsmachine.net.

Fundamentals

Keep it simple, stupid. You ain't gonna need it.

defmodule MyApp.Redix do
  @pool_size 5

  # How long, in seconds, to keep messages in the backlog
  @max_backlog_age 604800
  # How many messages may be kept in the global backlog
  @max_global_backlog_size 2000
  # How many messages may be kep in the per-channel backlog
  @max_backlog_size 1000

How to set up DNS records on gandi.net to use a custom domain on Github Pages

You would think it would be easy to find this information, but none of the Github or Gandi documentation is clear so I have recorded the required steps here.

Create the following A records:

@ 1800 IN A 185.199.108.153
@ 1800 IN A 185.199.109.153
@ 1800 IN A 185.199.110.153

low level primitives (in ascending abstraction)

• hypercore works with individual posts in an append-only feed
• hyperdrive abstracted filestore / works with files
• hyperdiscovery create p2p swarms for hypercores, hyperdrives, and hyperdbs
• hyperdb key-value database

higher level abstractions

• webdb database; basically a document(?) store
• dat-node built ontop of hypercore & hyperdrive, abstracts a bunch of stuff; less complex but also less flexible
