Er....There's new protocols with ipv6?

Stateless vs stateful vs Route Advertisement, etc doesn't take that long 
to understand, once you get into it, but that's the extent of the "new" 
networking methods

Most network engineers I know are spending their time convincing the 
boss they need to either upgrade most of their kit, or in come cases, 
replace it outright, as it's not v6 compatible.

That in itself is not a small task, and often requires a few months in a 
test lab and lots of work in EoI, Tenders, Assessments, etc. Couple that 
with the low number of ISP's that are doing native dual stack v6, and 
you're fighting an uphill battle, as the boss most of the time can't get 
it at home, so sees no benefit in spending the dollars to give the 
engineers "new toys".
