## Abstract

The Civilian Agency Acquisition Council and the Defense Acquisition Regulations Council (Councils) are issuing a final rule amending the Federal Acquisition Regulation (FAR) to require Internet Protocol Version 6 (IPv6) compliant products be included in all new information technology (IT) acquisitions using Internet Protocol (IP). IP is one of the primary mechanisms that define how and where information moves across networks. The widely-used IP industry standard is IP Version 4 (IPv4). The Office of Management and Budget (OMB) Memorandum M-05-22, dated August 2, 2005, requires all new IT procurements, to the maximum extent practicable, to include IPv6 capable products and standards.
