Linux IPv6

Steamrolling into the next generation of the internet, many of the linux developers from fortune 500 companies have, since 2005, been helping to pave the road for IP version 6, which will be the next generation of IP traffic. We've basically known about the coming of IPv6 for a long time, but so far we are still using our majority of internet traffic via IPv4. Why would this be? IPv6 has been an issue of discussion for over a decade, but still, while ARIN, APNIC, LACNIC etc are all IP providers and do provide IPv6 blocks, there is still no widespread use other than internally. Not so long ago, Linux has patched up and are now compliant with the Department of Defence compliance. All certification requirements have been taken care of.
