DOD Issues Updated IP Version 6 Implementation Guidance

The Department of Defense (DOD) has released an updated document establishing policy and outlining procedures for deploying and using Internet Protocol Version 6 (IPv6) in DOD information systems. The updated DOD Instruction, which took effect on December 17, 2024, was approved by Leslie Beavers, acting CIO at DOD and a 2024 Wash100 awardee.

The instruction outlines the phasing requirements for when IP-enabled assets on the DOD network must be upgraded to support IPv6. This includes all new networked information systems that DOD components use, which should be IPv6-enabled before their operational use.

The updated guidance is part of the DOD’s efforts to ensure a smooth transition to IPv6, which is designed to replace the current Internet Protocol Version 4 (IPv4). IPv4 is rapidly running out of addresses, and IPv6 is seen as a long-term solution to address the growing demands of the internet.

The DOD’s IPv6 implementation plan includes a phased approach that requires all new networked information systems to be IPv6-enabled by the end of fiscal year 2025. This applies to all DOD components, including the military services, defense agencies, and field activities.

The plan also outlines specific milestones for the transition to IPv6, including the following:

• By the end of fiscal year 2024, all new networked information systems must be IPv6-enabled.
• By the end of fiscal year 2025, all existing networked information systems must be upgraded to support IPv6.
• By the end of fiscal year 2026, all remaining legacy systems must be upgraded or replaced with IPv6-compliant systems.

The DOD’s IPv6 implementation plan also includes guidance on how to manage the transition to IPv6, including the use of dual-stack routers and switches, which can support both IPv4 and IPv6 traffic. The plan also outlines the role of the DOD’s IPv6 Transition Office, which is responsible for overseeing the transition to IPv6 and providing guidance and support to DOD components.

The updated instruction is part of the DOD’s ongoing efforts to modernize its information technology infrastructure and ensure that it remains compatible with the latest internet protocols. The transition to IPv6 is a critical step in this process, as it will enable the DOD to continue to operate effectively in an increasingly connected world.

In conclusion, the updated DOD instruction on IPv6 implementation guidance highlights the department’s commitment to staying at the forefront of technology and ensuring that its information systems are secure, reliable, and capable of meeting the demands of the 21st century. The transition to IPv6 is a significant step in this direction, and the DOD’s implementation plan outlines a phased approach that will ensure a smooth transition to the new protocol.
