This memorandum communicates the requirements for completing the operational deployment of IPv6 across all Federal information systems and services, and helps agencies overcome barriers that impede them from migrating to IPv6-only network environments. The strategic intent is for the Federal government to deliver its information services, operate its networks, and access the services of others using only IPv6. 0MB previously issued policy discussing the expectation for agencies to run dual stack (IPv4 and IPv6) into the foreseeable future; however, in recent years it has become clear that this approach is overly complex to maintain and unnecessary. As a result, standards bodies and leading technology companies began migrating toward IPv6-only deployments, thereby eliminating complexity, operational cost, and threat vectors associated with operating two network protocols.
