Some might also claim that there is a limitation in DNS
system because "port" numbers can not easily be returned
with an IP address. If that had been possible, then one IP
address could have been used and different TCP port numbers.

With the introduction of AAAA records into the DNS system,
there is now an opportunity to send 128 bit binary quantities.
Part of that quantity can be interpreted as a 32 bit IP address
and part can be interpreted as a port number.
