"Programmers can't get IPv6 thus that is why they do not have IPv6 in their applications"....



Many years ago the standard books on application network programming were
based on C language. Books such as "Adventures in UNIX Network
Programming", and Professor Comer's "Internetworking with TCP/IP Vol 3"
detailed how to write C programs using BSD sockets where binding to a
socket brought the program up in listening mode on an 2 tuple IP v4 IP
address/TCP well known port. Once the program opened and bound to a socket
"netstat -n" would show that program to be "listening" on the 2-tuple.

Do today's programmers still use basic BSD socket programming? Is there an
equivalent set of called procedures for IPv6 network application
programming?

On the practical side: Have all programmers created a 128 bit field to
store the IPv6 address, where IPv4 programs use a 32 bit field to store the
IP address? This would seem to be similar to the year 2000 case where
almost all programs required auditing to see if they took into account
dates after 1999.
