IPv6 INCORRECT rumors

Fixes all Internet problems
How? :-P
Noone uses it
There are so many users in Japan (ISP IPv6 service is available as well)
Asia and Europe are more active, US seems to be more optimistic about IPv4 address alloc
QoS problem is solved
Fields are reserved for QoS
QoS technology is still in its infancy, and needs more time to be stabilized
Security problem is solved
IPsec is mandatory
NAT will be gone, so IPsec can be used everywhere
However, IPsec itself has very difficult issue
IPv6 is not necessary since we have NAT
BIG NO!
Need hardware upgrade
In most cases, no.  Software upgrade is enough
