Sify.com is India's First IPv6 Enabled Portal

Sify's Entire Suite of IP Connectivity Services, Including Internet Access to
Enterprise Customers and MPLS-Based IP-VPN Services are IPv6 Enabled

CHENNAI, India, May 28 /PRNewswire-FirstCall/ -- Sify Technologies
Limited (Nasdaq National Markets: SIFY), a leader in Enterprise and Consumer
Internet Services in India with global delivery capabilities, announced today
that http://sify.com is the first commercial content portal in India to be
IPv6 enabled. This makes Sify a first mover in testing and deployment of IPv6
technologies and its associated services in India.
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 different Asia 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.
