Mapping the IPv4 internet

posted on 2019-12-27

Introduction

I decided to create an IPv4 map, which in turn was inspired by xkcd 195, but in Haskell.

Result

You can view the result in a separate window or in the iframe below.

Each pixel is an IPv4 address in the complete IPv4 space. Red means the host is only connectable on the HTTP port (80), green means the host is only connectable on HTTPS (443), yellow means both, black neither.
