According to Verisign’s Zone File Information site the total amount of .com/.net registered as of today is 119,700,000 million
As of March 31st the amount of .com/.net domains stood at 116.7 million domain names.
As of the March Verisign State of the Domain Report “.com/.net registrations grew 8.1 % over the first quarter of 2011″ or 8.9 million during the first quarter of 2012″
So we have at basically 6 months later an increase of just 3 million domains.
At that rate the total annual increase would be 6 million from 2011-2012 March quarter.
Its something we will keep on eye on but for now it looks like growth in the .com/.net is slowing substantially.
