# ColorPing

![IPv6 Canvas example](screenshot.png?raw=true)

## How does it work?

Each IPv6 address in a /64 IPv6 subnet is associated to one pixel with color (RGB) information.  

When an address is pinged, the corresponding pixel is changed on the canvas and displayed

to all viewers via a webpage.

## Setup

Run and assign a /64 IPv6 subnet to the created interface named `canvas`.

The program needs to run as root or with the `CAP_NET_ADMIN` capability.

Access the webpage where the canvas is displayed at: http://localhost:9090/

### Example

```

./ColorPing

ip addr add fdcf:8538:9ad5:3333::1/64 dev canvas

ip link set up canvas

```

### Ping format

```

????:????:????:????:XXXX:YYYY:11RR:GGBB

```

Where:

- ``????`` can be anything

- ``XXXX`` must be the target X coordinate of the canvas, encoded as hexadecimal

- ``YYYY`` must be the target Y coordinate of the canvas, encoded as hexadecimal

- ``RR`` target "red" value (0-255), encoded as hexadecimal

- ``GG`` target "green" value (0-255), encoded as hexadecimal

- ``BB`` target "blue" value (0-255), encoded as hexadecimal
