The Internet addressing system that we had been accustomed to using, IPv4, and which allowed us to be found on the internet for over 30 years has finally reached its limit.
The organization that assigns these addresses ran out of numbers on Wednesday. Fortunately the newer IPv6 system is up and running and appears to be seamlessly sliding into place and is a much much more robust system with a vastly greater capacity.
These addresses are what makes our devices, computer and smartphones unique to other points on the internet. A similiar type addressing system would be those communities that adopted 911 based location addressing, this addressing allows for a geo fix on each home and business to allow emergency responders to be able to locate the premise based on unique addressing. DNS servers have a similar approach but the layering topology has the ability to connect the entire world in its heirarchy.
The are actually more than one organization responsible for IP address issuance, ARIN is the group that handles North America. On Wednesday a entity had its request denied and the requestor was placed on a waiting list. Good luck if you are on this waiting list as anyone holding IPv4 address are not letting go of them or they are immediatley taking surplus addresses to the secondary market and charging pretty hefty fees. In fact we can expect those fees to begin to rise rapidly as has ARIN itself:
30 years ago the internet architechs had no idea of the success and universal adoption of the existing addressing system and as we reach this milestone addresses are still in high demand.
To allow for a perspective of the size of our internet addresssing system, IPv4 are created in groups of 4. One of Googles primary IPv4 DNS servers is 22.214.171.124 this system allows for over 4 billion addresses. The same server has a IPv6 address of 2001:4860:4860::8888 the IPv6 system allows for 340,282,366,920,938,463,463,374,607,431,768,211,456 or 340 trillion trillion addresses. Currently slightly over 20% of the US utilizes IPv6 with the US being the largest and fastest adopter.
IPv4 and IPv6 are able to work side by side without any issues for connecting with systems utilizing the other.
FInally!. The CURRENT release is availbale. I had been running the EDGE on a dev server and was very buggy. The first and most significant of the items list is that this is new installation only, no upgrades:
The second word of warning: cPanel does not plan at this time to support a 32 bit version of this distro since Red Hat does not provide one. More details will be provided as we progress.
cPanel & WHM version 11.50 introduces support for the CentOS 7 operating system. This document describes changes that we made to cPanel & WHM in order to accommodate CentOS 7's functionality, as well as known issues that relate to CentOS 7 installations. For more information about CentOS 7, visit the CentOS Project website.
To use CentOS as your server's operating system (OS), you can choose to install the cPanel-provided version or an independent distribution. The cPanel-provided version installs cPanel & WHM automatically the first time that your server reboots.
