IPv4 is Really Almost Out – The Time for IPv6 is NOW

On our Deploy360 blog we’ve been documenting the exhaustion of IPv4 addresses in each of the regional registry pools around the world. Yesterday, LACNIC announced that practically speaking there are no more IPv4 addresses available in Latin America and the Caribbean. What this actually means as we documented on our Deploy360 site is that they are down to the final 25% of their last /8 allocation, and are now in a mode of operation where allocations are far more limited and review of applications for new addresses is much more restrictive. It is starting to become impossible to get IPv4 address space using the traditional means around the globe.

As LACNIC CEO Raul Echebarria pointed out, the need for network operators to transition to IPv6 has never been more urgent. There is plenty of IPv6 address space available for anyone who wants to use it and there is more and more IPv6 being deployed in networks around the world. As we document on the World IPv6 Launch site each month, the number of networks with measurable IPv6 deployment continues to increase, and the amount of traffic from those networks to big websites around the world increases steadily as well. It is worthwhile mentioning that the most popular websites – Google, Facebook, YouTube, Yahoo!, and Wikipedia – have been using IPv6 for a couple of years now. We also observed that networks that have IPv6 deployed for their end users see a lot of IPv6 traffic on their network.

Transitioning to IPv6 is very possible and the exhaustion of IPv4 addresses in the LACNIC region just provides us with one more reminder that now is the time to make the transition. Our Deploy360 Programme can help you get started.
