IPv6 Considerations for TIC 3.0 (Internet Protocol Version 6 Considerations for Trusted Internet Connections 3.0) [open pdf - 526KB]
From the Introduction: "The transition of federal networks to Internet Protocol version 6 (IPv6) has been prioritized by the Federal Government since the release of Office of Management and Budget (OMB) Memorandum (M) 05-22, 'Transition Planning for IPv6,' in 2005. The memorandum calls for agencies to upgrade their infrastructures to use IPv6. In 2020, the Federal Government renewed its focus on IPv6 through the publication of OMB M-21-07: 'Completing the Transition to IPv6.'2 The memorandum specifically entrusts the Department of Homeland Security (DHS) Cybersecurity and Infrastructure Security (CISA) to enhance the Trusted Internet Connections (TIC) program to support the implementation of IPv6 in federal information technology (IT) systems. In order to support agencies, CISA has issued this TIC 3.0 and IPv6 network guidance to help agencies to secure their networks."
