单词 | IPv6 (Internet Protocol version 6) |
释义 | IPv6 (Internet Protocol version 6) The IPv6 specification grew out of the efforts of the IPng (IP next generation) Working Group to define a successor protocol to IPv4. Specified originally in IETF RFC 1883 (1995), since replaced by RFC 2460 (1998), IPv6 overcomes many of the limitations of IPv4, most notably with respect to address space, integration of application level protocols, quality of service (QoS), and security.The total size of the IPv6 datagram, including the header, is increased beyond the IPv4 limit of 65,535 octets to support jumbo payloads. At a minimum, all network links must support a maximum transmission unit (MTU) of at least 1,280 octets.
