Overview of IPv4 and IPv6 Call Set-up
Using AF_INET6 Socket for IPv6 Communications
Chapter 530
2. The search finds an IPv6 address for host6 in the hosts database, then getaddrinfo
returns the IPv6 address 2fee:1212::200:2bff:fe2d:0c2c.
3. The application opens an AF_INET6 socket.
4. The application sends information to the 2fee:1212::200:2bff:fe2d:0c2c address.
5. The socket layer passes the information and address to the UDP module.
6. The UDP module identifies the IPv6 address and puts the
2fee:1212::200:2bff:fe2d:0c2c address into the packet header and passes the
information to the IPv6 module for transmission.
