My best guesses in no particular order, but, based on the feedback I receive
from many of these organizations when I talk to them at a variety of trade shows
2. Fear of the unknown (We don't know IPv6. IPv4 NAT is familiar. The
devil we know...)
a. "There is no multihoming solution in IPv6"
b. "The lack of NAT in IPv6 makes it fundamentally insecure"
c. "We could never implement a protocol without address obfuscation"
d. "PCI requires us to use NAT" (There is actually a proviso in PCI
for equivalent compensating controls).
4. They went to someone's IPv6 security lecture and came away with
the sound bite "Don't deploy IPv6 on any production network unless
you absolutely have to."
I'm sure these are just a few of the reasons. Notice that most of them can
be solved primarily by education which is why I spend most of my time
working on IPv6 education. However, it is exceedingly hard to teach those
unwilling to learn and corporate IT departments seem to specialize in
having a tremendous resistance to learning anything that doesn't look
like their current environment.
