Websockaddr_in6 structure holds IPv6 addresses and is defined as a result of including the header. sin6_family overlays the sa_family field when the buffer is cast to a sockaddr data structure. The value of this field must be AF_INET6. (2Byte) sin6_portcontains the 16-bit UDP or TCP port number. WebThe header shall define the in6_addr structure that contains at least the following member: uint8_t s6_addr [16] This array is used to contain a 128-bit IPv6 address, stored in network byte order. Webinet6 is a collection of protocols layered atop the Internet Protocol version 6 (IPv6) transport layer, and utilizing the IPv6 address format. The inet6 family provides protocol support for the SOCK_STREAM, SOCK_DGRAM, and SOCK_RAW socket types; the SOCK_RAW interface provides access to the IPv6 protocol.
