IPv4 address hits its limit

Posted on September 9, 2012 10:18 am

IPv4 addressing, a system that give computer connected to the Internet a unique address has finally come to an end after RIPE NCC, the consortium of internet organizations that oversees the system in Europe this morning it had used the last block of 16.8 million addresses. IPv6, a new addressing standard that offers around 340 trillion unique addresses will take over. I know majority of end users are allocated dynamic address which are re-issued to another user when they drop their connections.IPv6 vastly increases the amount of address space, helping to enable an exciting turning point in society as Internet connected devices become increasingly more sophisticated and commonplace. RIPE NCC said that when the Internet was first designed it seemed highly unlikely that IP address space would ever be an issue. However, the limitations of the pool of IPv4 address space became clear over time, and in the last few years we have been monitoring supplies closely, preparing ourselves and all stakeholders for the next stage of the Internet.

Most ISP have the IPv6 capabilities already. For those who don’t know, Tablets like iPad and Galaxy Tab as well as smartphones like iPhone typically connect to other services on the Internet and don’t offer services for others to use e.g. web or email servers and therefore, they don’t need their own registered IP addresses. Such devices can be issued with private IP addresses and many of them can then use a single registered IP address and to my knowledge several mobile network operators already do this.One thing that I have studied and is a problem with IPv6 is that all those that already have sufficient IPv4 addresses allocated are not bothered about migrating. Many will find it difficult to get resources to spend money on a migration which offers no tangible advantage and I bet few are going to move to IPv6.
