Why would you want to waste 79228162514264337593543950336 addresses on a loopback? 

More seriously, why does this discussion only briefly mention IPv6? Every
client comes with it (aggressvely) enabled -- it is there despite the
fat / happy parts of the networking community sitting on their legacy
space and laughing at Asia.

I've had, as mentioned earlier, a "cisco graduate" as intern and then
colleague for a year now. He's a fast learner, and that was needed. No
v6. Not much MPLS. No ISIS. Barely eBGP. No iBGP, especially not in
conjunction with a link-state IGP. Lots of RIP, Flame Delay and EIGRP. 

There are two problems; 

* The academic community is either outdated or married to a
  vendor-specific course -- and that marriage is not very 
  academic, IMNSHO. Academia must be vendor agnostic.

* The vendor courses are too enterprisey, and an outdated 
  enterprise at that. There is no course in "running a 
  sensible chunk of the Internet". 

And this in a world where the largest innovation the last 5 years is
abstraction (as in virtualisation and to some extent SDN). Not in 
protocols. Should be reasonably easy to keep up.
