Sify.com is India's First IPv6 Enabled Portal

Arvind Mathur, Chief Architect, Sify Technologies Limited, said, "The decreasing availability of IPv4 addresses makes it imperative for users to migrate to the IPv6 space eventually. As pioneers in services over IP in India, Sify has addressed this critical need to augment its IP address resources. Our capabilities in IPv6 migration are in line with our vision to develop future proof solutions for customers."

Today, Sify's entire suite of IP connectivity services, including Internet access to enterprise customers and MPLS-based IP-VPN services are IPv6 enabled. This ensures that Sify's customers can transition and migrate from a basic IPv4 based network service to IPv6 Next Generation Network (NGN) with dual-stack [IPv6 & IPv4] support. Speaking about the migration process, Arvind said "Migration to IPv6 requires careful planning that adapts, integrates and helps co-exist with the current network environment".

Sify has also been participating in various projects at international forums to encourage the adoption of IPv6.

Dr. Sathya Rao, Director of Telscom,Switzerland , coordinating the European funded co-operation project , 6CHOICE (India-Europe Cooperation to promote IPv6 adoption; http://www.6choice.eu), said, "We are very happy to have Sify, an early adopter of IPv6 in the provision of future IP services, as a partner in the project. We believe in their capabilities in adding value to 6CHOICE and to the Internet industry at large, and expect others to follow their initiative."

A recent survey commissioned by APNIC and conducted by KPMG with 601 respondents from 44 differentAsia Pacific economies has revealed that nearly two thirds of the respondents are not adequately prepared for the transition to IPv6. Calling for action on the issue, Arvind added "We urge all organizations integral to the Internet infrastructure to adopt IPv6 early-on so as to ensure a smooth migration, as well as to circumvent any potential scalability issues in the future."

The IPv6 space has 340 undecillion addresses; APNIC has assigned Sify a 0.00000002% share, which by itself constitutes 79.22 octillion addresses.

The abundance of IPv6 addresses will help Sify roll-out consumer services supporting digital home networking, IP surveillance and other services supporting mobility based applications. Sify is currently working on IPv6 deployments that include Video Streaming over IPv6 networks and enabling Mobile phones to support IPv6 applications.
