Cost of operating v4/v6 combined for some time includes, among other

to work both protocols on too many devices.
4. Cost of documentation and training for Help Desk personnel.
5. Cost of "Linksys WRT54G-IP6" or equivalent because of increased
memory and programming requirements.
6. Cost of software maintenance for network core router software --
didn't we just go through getting rid of DECnet, SNA, IPX/SPX, and
AppleTalk because of this, among other reasons??
7. Marketing cost of being perceived as "obsolete".
8. Opportunity cost due to more complex delivery configurations slowing
9. Cost of "IP Naming and Addressing Management" due to multiple
protocol complexity -- didn't we just go through getting rid of DECnet,

Let us not forget that network vendors are now capitalising on the
requirement to purchase expensive licensing for such features as native
IPv6 routing and 6PE, on their mid to high end kit.
I dont feel this sort of behaviour is helpful, I can understand asking
for licensing fees for L2VPN/L3VPN technologies since these are products
that service providers can levvy a reasonable charge for, but to charge
for IPv6 routing capability alone, at the time where the discussion of
which has never been so serious, leaves a bit of a bad taste in one's mouth.
