zmap is an interesting tool which allows scanning all public IPv4 addresses (IPv4 Internet) in about 45 minutes:

To quote from Tech Week Europe<http://www.techweekeurope.co.uk/news/zmap-internet-scan-zero-day-125374>:

The tool is only possible because the Internet is currently all squeezed into the (comparatively) small IP version 4 (IPv4) address space, leaving empty the much larger IP version 6 (IPv6) address space, where a brute force scan would be impossible using current hardware.  "We are living in a unique period", the researchers said in their talk. "IPv4 can be quickly, exhaustively scanned - IPv6 has not yet been widely deployed."

I found this interesting because from a security vantage point you could argue that IPv6 is superior in the sense that you can't brute force scan it (Entire IPv6 Internet) whereas with IPv4 you can.  Do you think this constitutes an IPv6 advantage?
