Given the global lack of available IPv4 space, and limitations in IPv4 extension and transition technologies, this document deprecates the concept that an IP-capable node MAY support IPv4 _only_, and redefines an IP-capable node as one which supports either IPv6 _only_ or IPv4/IPv6 dual-stack. This document updates RFC1812, 1122 and 4084 to reflect the change in requirements.
