Yesterday, the [IPv6 Canvas](https://blog.tugzrida.xyz/2023/02/06/introducing-the-ipv6-canvas/) was pushed to the public.
|
|
|
|
Of course, as soon as I learned of this, I threw together a script to place my domain `ewpratten.com` on the canvas for all to see.

## How I'm doing this
|
|
|
|
The code is [public](https://github.com/ewpratten/v6-canvas-writer) for anyone wanting to do this themselves, and the process for getting everything working was pretty simple.
|
|
|
|
1. I designed the graphic in a random online pixel art editor
|
|
2. The design was converted to a bitmap
|
|
3. I have a Python script that can read an arbitrary bitmap and convert it to a list of IPv6 addresses
|
|
4. Hundreds of `ping -c 1` processes are spawned in the background to write the image to the canvas
|
|
|
|
This script is executed via a Cron job on one of my edge routers for maximum IP nerdiness.
|
|
|
|
### Why ping?
|
|
|
|
I considered doing this with some clever `mtr` commands, or even crafting the ICMP ECHO packets straight from the script, but that was slightly too much work for the 5 minutes I had before work this morning.
