There have been claims that the Internet running out of steam for at least a decade. One of the most prevalent fears today is that we’re going to run out of IPv4 addresses in 2011. Actually it is more than a fear, it is a certainty. Fortunately, there are many techniques that have been deployed for a number of years to limit the consumption of these precious addresses, like NAT.
Still, the move from the old addressing scheme to IPv6 needs to take place. On June 8th of this year, there is a plan to have a World IPv6 day, where the capabilities of the new addressing will be exercised.
“The trial — dubbed "World IPv6 Day" — requires participants to support native IPv6 traffic on their main Web sites on June 8, 2011. Leading content delivery networks Akamai and Limelight Networks also committed to the IPv6 trial, which is being sponsored by the Internet Society.”
Businesses need to understand the implications of IPv6 on their environments and have a migration plan. Fortunately, hardware manufacturers have been thinking about this for a decade so most platforms should support it. Watching the news for how these events transpires should help with planning.
