Convert your IP Address to RGB Color Values

A color in the RGB color model is described by indicating how much of each of the red, green, and blue is included. The color is expressed as an RGB triplet. In computers, the component values are often stored as integer numbers in the range 0 to 255, the range that a single 8-bit byte can offer.

An IP address is a 32-bit identifier assigned to a host that uses the Internet Protocol. The IP address is represented by four octets (8-bit fields). In decimal form, an IP address consists of four fields separated by dots, where each field contains a value in the range 0 – 255.

A web app for this

I suddenly realized that the I could play around a little with this. If I took the first three fields in an IP address and used them as RGB values, it would create a custom color code for that IP address.

Wait, what about the fourth field in the IP address? Well, that could be used as a alpha gradient, as in the rgba() function used in CSS for example. I could also use the last three fields in the IP address, instead of the first three, but didn’t.

Update: After a tip from a friend, I included a quick algorithm to draw a quadrilateral based on the same IP address numbers.

I put this up at https://apps.hoyd.net/ipcolor/ where you can try yourself.

The source code for this can be found on GitHub.
