Probably wouldn't take too long to check what % are pingable, which would give you a lower bound.

- axod 16y agoBy my calculations, you'd only need to spin up 50 or so amazon instances, and they could cover the entire IP space in a day doing 1k pings/second each. That's pretty doable.
- jefe78 16y agoThats still not an insignificant amount of time/effort. I'd love to see someone do this though!
- zaphoyd 16y agoThese guys have been mapping the IPv4 space via ping over time (since 2003) and have an interactive browsable map that also shows blocks marked for localhost/private networks/multicast, etc and which registrars control which regions. It is pretty neat. Most recent data is Nov 2010. Since then the 11 /8 blocks that show as free have been allocated. http://www.isi.edu/ant/address/ http://www.isi.edu/ant/address/
