Actually, IPv4 and IPv6 *are* completely different (although related)
protocols. For sure, the most obvious difference between them is the
length of the addresses, but there are other differences as well. The
header formats are different, and there are fundamental differences in
how they deal with options, routing, MTU, traffic flows, etc. Wikipedia
does a decent job comparing the two
(http://en.wikipedia.org/wiki/Ipv6#Comparison_to_IPv4).

To the best of my knowledge, the first RFC describing what we now call
IPv4 was RFC 760, published in January 1980. This was updated by RFC
791, published in September 1981. I'm not sure when the first
experimental versions were deployed, but it's absurd to say that IPv4
was in use (heavy or otherwise) in the 1960s.

People often say "IP" when they mean "IP address" in casual
conversation. "I can't reach foo.com, can you try pinging it?". "OK,
what's the IP?" It's sloppy, but lots of casual conversation is sloppy,
and people figure out the meaning from context.
