250 million-plus reserved IPv4 addresses could be released – but the internet isn’t built to use them

Sure, IPv6 supports multiple addresses on an interface. Which source IP address does your application use and how does it find out?

Don't stone the DNS heretics

RTFM

You might want to look at the manpage for inet_addr(), in particular the sections that describe handling of "a", "a.b", "a.b.c" and how the "parts" can be specified. The behavior you're complaining about has existed in inet_addr() since before the DNS existed.
