|ipv4 is just a new nickname for the good-n'-ol' IP protocol. I suppose

It's not "new nickname".  The IP version currently in use was allways
version 4 (that's what the first field of every IP packet zooming near
you says).  It's just that the distinction in directory names was made
explicit in 2.* to make way for the new IPv6 (aka "IPng" - "IP next
generation").

BTW, IPv6 is not just an extension, it has two major important
advantages over IPv4:

1. Much larger address space (128 bits per host)
2. Security options (authentication and encapsulation).

It's supported in 2.1, as Marc pointed out, and it is being testted
over the existing IPv4 Internet using encapsulation.  I suppose it is
relatively simple to take part in the experiment (look in
http://playground.sun.com/ipng for everything about IPv6), and use it
as "private network" among Linux users.  The more people test the
Linux IPv6 code the better.
