2. Delivering locally ...with a history of successful investment in the region... • Operating globally and delivering locally: • +180 Points of Presence • +41,000 customer connections • 7 network operations centers providing monitoring and proactive diagnosis 24x7 • 5 data centers in Brazil, Argentina, Colombia, Mexico and Venezuela • Security operations center in Sao Paulo Current Analysis “BT's ambitions in professional services are backstopped by several large data centers in the region that can provide outsourced/hosted services and applications for clients.” 2

4. Are you aware… IANA ran out of allocatable addresses in Feb 2011 The IPv4 address space ismanaged by IANA and five regional internet registries RIR APNIC’sIPv4 allocation was exhausted on April 15, 2011

5. What the EU is saying Business advantage to be gained from IPv6 “ Amongst other things, IPv6 allows almost anything to be connected to the Internet permanently. Security mechanisms and improved support for Quality of Service are part of the protocol.” ErkkiLiikanen EU Enterprise Commissioner

6. What the analysts are saying IPv6 will grow during the next investment cycle Gartner predicts that, by 2015, 17% of global Internet users will use IPv6, with 28% of new Internet connections running the protocol.* Most of the IPv6 adoption will be from mobile users, whose devices are not managed by DDI systems. *(see "Internet Protocol Version 6: It's Time for (Limited) Action").

7. IPv6 grows the Internet Dealing with Asia Pac customers Explosive growth in internet traffic in 2011 • Asia Pac received less than 10% of the available IPv4 space forcing them to adopt IPv6 • International business requires the capability to handle inbound IPv6 • 2 billion internet user • 2 billion IPv4 users • 0 IPv6 users • Tablet sales outnumbered PC sales IPv6 is already embedded in applications and devices operating in your network Technology drivers for IPv6 By 2015: • The development of Smart technologies and environments rely on IPv6 • M2M technologies will drive IPv6 demand • 4 billion internet users* • 2 billion IPv4 users • 2 billion IPv6 users • Proliferation of connected devices

8. IPv6 Demand • The rate of IPv6 traffic levels worldwide has increased since IPv6 World Launch on 6th June 2012 . IPv6 adoption varies by country and influenced by small number of large deployments. A major contributor being the permanent IPv6 enablement by the top content providers (Google, Facebook, Youtube, Yahoo, Wikipedia, Bing etc.) • Early adoption by academic institutions (some show internal levels of IPv6 traffic over 50%). • US federal agencies mandated to IPv6 enable public facing websites by September 2012. • IPv6 adoption in Latin America is still very low Currently more than 3% of Google’s users are already IPv6. It may seem little, but in September 2013 was only 2%. This shows that the use of the protocol has accelerated. The predictionis IPv6 adoption hits double digits in 2014

9. IPv6 – Y2K all over again ????? …you could see an erosionin competitive advantage and subsequently customers Your business will still continue to operate… • However... • No

10. The risk of doing nothing? • Experts say your online presence may not be reachable by a growing number of customers and supply chain/partners around the world • Missing the investment cycle leads to remedial action later • Advanced functionality in IPv6 may offer a business and competitive advantage • Loss of potential improved operations and security • Attrition due to lack of challenging IT/Ops work environment "The risk is that you are lights out for your customers," Hankins* says. "The risk is that you are off the Internet to a small but growing population." *Greg Hankins, Global Solutions Architect for Brocade

11. Consequences of NOT deploying IPv6 Company web and email servers With IPv4 addresses only IPv4 users Internet With IPv4&6 addresses IPv6 users Your business will be unreachable by IPv6 users!

13. Why careful planning is required IPv6 touches every part of your organisation: Strategy Policy and support Management • Strategic planning • Buying strategy • Investment cycles • Change management • Security policy • Services and processes • Training • Application support • Hardware/ OS • Systems • Monitoring • Reporting and management Preparation is required NOW Investment is required NOW
