Preparing for IPv6 migration
What is IPv6 The current Internet Protocol (IP) addressing system IPv4 will eventually run out of addresses IPv6 is a new protocol that has been introduced that will, over time, fully replace IPv4 IPv6 offers many new capabilities that will benefit Canadian organizations including enhanced security and advanced mobile capabilities Page 2
What is happening with IP addresses? IPv4 addresses are running out If an atom were used to represent the 4 billion IPv4 addresses, the 16 billion billion IPv6 addresses is equivalent to an 80-tonne whale Page 3
Why this is happening Explosion of wireless and wireline devices that require IP addresses tablets, GPS, phones, PDAs, appliances Growth in smart networks to address vertical needs (health, transportation, home, etc.) Exponential growth in developing nations requiring vast quantities of IP addresses Page 4
How this impacts businesses Opportunities Productivity (mobility) Enriched monitoring, reporting, tracking, command-and-control Connect to organizations that are already transitioning to IPv6 Future-proof legacy services I P V 6 Challenges Adoption and migration Security changes IP based network equipment setup and retrofits Software and application upgrades Migration and overlap timeline Page 5
What you need to know 1. While Bell will continue to support IPv4, over time, applications will be increasingly built on the IPv6 platform (e.g. for machine-to-machine communication) 2. You may have to align with government or corporate policy that requires the use of IPv6 3. Some of the multinational companies that have policies and mandates around IPv6 may require you to be IPv6-ready so companies need to make IPv6 migration plans accordingly 4. You may not be able to purchase new IPv4 addresses 5. You need to revisit your security controls as a result of this transition 6. You may want to take advantage of the enhanced security capabilities (strong IP-layer encryption and authentication) provided with IPv6 Page 6
What you need to know (Con t) 7. You may require IPv6 to enable new content and applications requiring the use of many machines/devices 8. Bell will continue to support IPv4 services well after the exhaustion of IPv4 addresses, with a dual-stack approach that allows continued communication between IPv4 and IPv6 for years to come 9. As a result, when IPv6 is introduced, customers can move to IPv6 at their own pace and our IPv4 customers will be able to use their existing IPv4 addresses with the same Internet reach that they have today 10. You may want to establish a governance team and process to ensure a smooth transition A successful transition to IPv6 will require significant planning and strategy Page 7
Benefits of transition to IPv6 Cost savings architectural changes associated with the transition to IPv6 will create greater cost efficiencies Growth increases the range of goods and services that organizations can provide and opens new markets, as the availability of unlimited addresses allows exponential growth in the devices that can be connected to the Internet Page 8
Benefits of transition to IPv6 (Con t) Enhanced security and compliance Vulnerabilities that were present in IPv4 were removed from protocol e.g., broadcast-based attacks, man-in-the-middle attacks that can intercept and modify traffic prior to being sent to its destination Improved mobility maintain VPN sessions more efficiently, avoiding the need for repeated logins and minimizing credential compromise Privacy extensions allows your device to change IP addresses frequently, to remain more anonymous Additional IPsec encryption software no longer as it s built into the network stack Encryption is also end-to-end, from device to device IPv6 adoption will allow your business to communicate better in a globally networked world Page 9
We support our customers Bell will offer support for customers who want to get started on their IPv6 migration now As you migrate, we will provide continuing IPv4 interoperability We can help you develop a secure and complete transition plan with our phased approach to IPv6 adoption Bell has made significant investments to upgrade our network infrastructure and our products and services Page 10
Key IPv6 transition considerations To ensure a successful IPv6 transition, you ll need to: Look at your current IPv4 and IPv6 capabilities and security needs Define your end goals Design a secure infrastructure and network Test systems and services in a dual-stack and/or IPv6-only environment Bell can help you develop your implementation roadmap with a secure, phased approach to ensure success Page 11
How Bell can help you transition Bell offers IPv6 Professional services to support you every step of the way: Network traffic and threat discovery Business strategy planning Security training service Readiness services Proof-of-concept/Simulation plan Implementation (production piloting) Network optimization and diagram refresh services Identify IPv6 enabled devices that could attack the IPv4 network with malicious traffic Determine drivers and plan business requirements Learn how to secure network against threats, analyze and react to denial-of-service attacks and implement security standards and processes to protect it Inventory and map devices and software, assess what changes are needed and initiate design Establish and document the testing environment, provide knowledge transfer for customer s IT team Deploy pilot sites to validate integration across systems and networks Provide support for incremental IPv6 changes and provide on-going diagram refresh based on network activities Page 12
