BANGALORE, INDIA: There will be serious implications if enterprises don't migrate to IPv6 and these implications will become evident as the IPv6-only portion of the Internet begins to grow, warns John Curran, president and CEO, American Registry for Internet Numbers (ARIN).

Experts warn that IPv4 will be depleted by early 2011, and this is the right time to migrate to IPv6, which is said to support four times the number of addresses than its predecessor.

Shridhar Luthria, manager, channel development, ResellerClub, Directi, says, "The rapid success of Internet in India has led to an accelerated consumption of IP addresses, and has led to the anxiety about shortage of IP addresses in the coming years in the country."

Every business today has an online presence and if they miss the bus to IPV6 today they are going to lose the game tomorrow.

"Enterprises and corporations may not be able to communicate with certain critical government resources, clients, and potential customers. Organizations that provide services over the Internet may experience customer and/or revenue losses if they do not update their offerings to include IPv6," adds Curran.

Today there are many products that are IPv6 enabled. Internet giants such as Google, who enabled IPv6 access to YouTube, and Microsoft, whose Vista and Windows 7 and latest OS are IPv6 by default, have already made the move. However, there are lot more, who haven't done so. As per reports, only .01 percent of IPv6 pool has been used up so far.

Now, here is a report from GigaOm's Blog, posted in 2005, where he says 'Asia says yes to IPV6, US says whatever', /

However, coming to reality, there are about 2,500 organizations in the ARIN region (Canada, the United States, and parts of the Caribbean) who will migrate to IPv6 by 2012. Whereas, India has only 33 IPv6 blocks assigned to it so far (IPv6actnow.com).
