The Depleting IPv4 address space had been of concern since nearly a decade. The concerns transformed into efforts that lead to the evolution of IPv6.

With the current pace of depletion of IPv4, we would run out of address space within a year. The latest usage report is out which gives us exact usage numbers: 80.5% address space is used, up from 75.3% of last year (2009 begining).

As of Jan 1st, 2010, the number of unused IPv4 addresses is 722.18 million. On January 1, 2009, this was 925.58 million. So in 2009, 203.4 million addresses were used up. This is the first time since the introduction of CIDR in 1993 that the number of .. Read Further »

After, IPv4, IPv5 was a literal Realtime protocol which was not practical to implement, hence was a failure, never came out of paper. We had high hopes for a Internet standard that emerges after a complete decade of development life cycle.

It never came upto the Expectations

IPv6 the so called “next-generation” Internet protocol isn’t keeping too many U.S. CIOs and network managers up worrying at night. But the story is two folded with an Irony.
