There has been little or no reason to adopt v6 so far, other than as an alternate means of connectivity to reach what, geek operated mail, ftp and rsync servers for Linux distros and assorted open source software? With some majors like Google starting to adopt it, and with only a few years left for a v4 aftermarket, carrier grade nat etc to have any effect, and with newer generations of devices yet to ship with v6 only stacks but that's a matter of time... That is when you will start to see the true uptake and growth of v6. I rather suspect what i predict may well happen in our lifetimes, or even in the couple of decades of years before I retire --srs (htc one x) On 28-Jun-2013 1:37 PM, "Gert Doering" <<a href="mailto:gert@space.net">gert@space.net</a>> wrote: > > Hi, > > On Fri, Jun 28, 2013 at 01:27:19PM +0530, Suresh Ramasubramanian wrote: > > I know the size of the v6 namespace > > Remember that we are currently working with a smaller effective size..
