MEMORANDUM FOR SEE DISTRIBUTION
SUBJECT: Chief Information Officer Guidance for the Army’s Transition to Internet
Protocol Version 6
1. References. See Enclosure 1.
2. Purpose. This memorandum communicates the requirement to implement and
transition to Internet Protocol Version 6 (IPv6), assigns responsibilities, and provides
guidance to conduct transition planning and methodically prepare for the operational
deployment of IPv6 across all Department of Army (DA) networked information systems,
devices, services, and applications that use internet protocol (IP) communications.
3. Background. IPv6 is the next-generation IP that is essential to supporting the
continued growth of the Internet, presenting a strategic opportunity to enhance IP
mobility and deliver information services with greater efficiency. Taking these benefits
into account, and in accordance with Federal and Department of Defense (DoD)
mandates per references 1a and b, it is the strategic intent of the Department’s end
state as an IPv6-only environment.
4. Applicability. This memorandum applies to all Army stakeholders to synchronize and
integrate IPv6 implementation efforts (for example, Compos 1, 2, and 3, USACE, AMC,
other ORGNETs, organizations receiving Non-Appropriated Funds (NAF) or Army
Capital Working Funds (AWCF), and other Army organizations as required). In
accordance with reference 1c, it includes all classified and unclassified information
systems, devices, services, and applications that use IP communications. These
technologies are more broadly referred to as “IP-enabled assets” throughout this
memorandum.
5. Policy. Beginning Fiscal Year (FY) 2025 all new Army information systems that use
IP technologies must be IPv6-enabled before implementation and operational use.
a. By the end of FY 2025, networks and systems that cannot be transitioned to
IPv6-only; must be running in a dual stack (IPv4 and IPv6) environment.

SUBJECT: Chief Information Officer Guidance for the Army’s Transition to Internet
Protocol Version 6
b. Army information systems that cannot be transitioned to IPv6 must be identified
and justified through an approved Plan of Action and Milestones (POA&M) schedule for
replacing or retiring these systems by end of FY 2025 per reference 1a.
c. In rare circumstances where there will be difficulties conforming to IPv6 transition
requirements, the responsible system owner should submit a waiver request to the
Army’s Unified Network Council (AUNC) to waive this requirement. The AUNC will
consider waivers on a case-by-case basis. In such cases, the purchasing agency shall
request documentation from vendors detailing explicit plans (for example, timelines) to
incorporate IPv6 capabilities within their offerings (re: M-21-07, Adhering to Federal
IPv6 Acquisition Requirements).
d. Additional guidance for Operation Technology (OT) systems will be addressed in
future policy as needed.
6. Responsibilities.
a. Army Chief Information Officer (CIO) will serve as the Army’s IPv6 Agency Lead
responsible and accountable for IPv6 policy and governance, develop IPv6 related
policies, and report on transition progress to the DoD CIO IPv6 Working Group.
b. HQDA, Deputy Chief of Staff G-6 (DCS, G-6) will serve as the Army’s IPv6 Lead
Implementor responsible for the development and execution of the Army IPv6
Implementation Plan, which describes the approach to implement and transition to an
IPv4/IPv6-hybrid environment in support of the IPv6 milestones identified in this
memorandum. The Army’s end state goal is an IPv6-only environment.
c. Army Cyber Command (ARCYBER) will develop an Army IPv6 Address Plan that
is compliant with the Department of Defense Internet Protocol Version 6 Address Plan,
Version 1.3 Updated December 2021. The Address Plan should consider clear and
concise mapping of the addresses to the network’s physical topology to maximize
efficiency.
d. Assistant Secretary of the Army (Acquisition, Logistics, and Technology) (ASA
(ALT)) should provide appropriate direction to Program Executive Offices and Program
Managers to design, build, test, and field IPv6-capable Information Technology (IT),
using the DoD Information Technology Standards Registry (DISR) mandated IPv6
standards.

e. System Owners, Command Administrators, or Resource Managers will verify
record profile data and resource data on IP-enabled IT systems in the Army’s
authoritative data source (ADS), Army Portfolio Management Solution (APMS) as
updates occur.
7. Duration.
a. This guidance is effective upon signature and remains in effect until superseded,
rescinded, or incorporated into Army Regulation (AR) 25-1 (Army Information
Technology), reference 1d.
b. The Office of the CIO will ensure this memorandum is reviewed no later than 1
October of each calendar year for supersession, rescission, or inclusion in the next
edition of AR 25-1.

GLOSSARY
TERM DEFINITION
Army Portfolio Management
Solution (APMS)
APMS contains, and is the authoritative data source
(ADS) for the Army’s inventory of active IT investments
and their associated systems and applications, as well
as information system and application hosting
environments.
IP-enabled asset Any information system, device (i.e., routers, servers,
switches, firewalls, printers, computers, etc.), service,
or application that uses internet protocol (IP)
communications.
IPv6-capable Refers to an IP-enabled asset that has correctly
implemented a complete set of IPv6 capabilities. The
DISR mandated standards for IPv6 provide detailed
technical requirements for IPv6 capabilities for distinct
product types.
IPv6-enabled Refers to an IP-enabled asset in which the use of
IPv6 is “turned on” for production use.
IPv4/IPv6 dual-stack Refers to the state of an IP-enabled asset when both
IPv4 and IPv6 protocol stacks are operating in
parallel, and network nodes can communicate via v4
or v6.
IPv6-only Refers to the state of an IP-enabled asset when IPv4
protocol functions (addressing packet forwarding) are
not in use. The DISR mandated standards for IPv6
defines technical requirements for a product to be
capable of operating in IPv6-only environments.
Purchasing Agency is any state organizational unit or administrative body
that receives goods or services from a vendor.
Temporary Waiver Waivers with a CIO designated expiration date. A
temporary waiver enables the system managers to
wait until an appropriate time in the systems life cycle
(e.g., modernization) to incorporate a new data
standard.
Permanent Waiver Waivers granted for the life of the system.
