IPV4 address will be over by 2011:

Exactly (check out this link to know how many days) www.penrose.uk6x.com this much days available to assign IPV4 address to new users. This calculated using the new allocation of user rate. This rate will increase soon so IETF fear that the addresses will be worn out by 2010.

More than 85 per cent of the available addresses have already been allocated and the rest will run out by 2011, according to a prediction by the Organization for Economic Cooperation and Development (OECD).

IP addresses are so basic to the success of the Internet that we really do not need to know a website's domain name if we know their IP. In fact, domain names are only a convenience for people to remember the addresses easily to type, say for e.g. www.google.com has IP address of 216.239.39.99. It is tough to remember all the IPV4 address so only we give names for the IP address.

When the IPV4 address scheme was introduced in 1981, there were hardly 500 computers connected to the Internet. So the address makers at that time allowed for four billion addresses, thinking they would last forever. But those address lost for only 30 years.

When the addresses are ran out, Internet speeds will drop and new connections and services (such as Internet phone calling) will either be expensive or simply impossible to obtain.The solution to the shortage is to upgrade to a new address protocol IPV6. The IETF has introduced IPv6, more than a decade ago, providing enough addresses for billions upon billions of devices as well as improving Internet phone and video calls, and possibly even helping to end e-mail spam.

The problem is that the new system is not really compatible with the Internet of today. If, for example, Google wants to support IPv6, it will need to build a whole new IPv6 web service, complete with new domain names, servers and bandwidth. Everyone needs to build a new web service for IPV6. That costs will run into billions of billions of billions...

It's actually not that hard to add IPv6 to existing systems, and won't cost "billions and billions"...

In fact, your example (Google) already did it:

Most them started using IP4 few years before itself.
