Security considerations for Internet Protocol version 6 (ITSM.80.003)

Exponential growth in the use of Internet-based technologies to deliver modern business services and applications is linked to the depletion of globally available Internet Protocol version 4 (IPv4) addresses. The Internet Protocol version 6 (IPv6) addressing scheme was designed by the Internet Engineering Task Force (IETF) to replace IPv4, and it offers significantly larger private and public address blocks to adequately support modern enterprise and non-enterprise needs. This publication highlights critical security considerations for IPv6 deployments within GC networks. GC departments must design transition plans to support IPv6 addressing while ensuring operational and security risks are mitigated.
