Hi Folks,

I'd like to share with you some recent work I've done on visualizing
the routing table.

As the page says, I use the routeviews snapshots to create maps
showing the locations and size of each prefix in the table.  The
IPv4 address space is mapped into 2-D with a Hilbert curve (as seen
on xkcd).  I have maps for snapshots going back to early 2004 and
an animation that shows the evolution over time.


Is the older pictures based on older allocation data, or present-day data?
