Tool to generate a map of the ipv4 address space using hilbert curves
hilbert.py reads a newline seperated list of ips that gets colored white on
the resulting image. It reads either from a file specified as argument or from stdin.
The resulting image has the dimensions 65536x65536 making it difficult to view as a whole in
conventional image viewers. An example for generating tiles for viewing with as a zoomable map
can be found in generate_tiles.sh. The resulting map can be found under https://ipv4map.github.io (source)
Obtaining data on the whole ipv4 address space can be difficult, because most
ISP’s don’t like aggressive portscanning. Fortunately censys.io provides
their datasets for free download. An example script using their datasets can
be found in download.sh.
