There's been a lot of on-and-off discussion about v6,
especially about security and operational concerns
about some aspects of IPv6 deployment, specifically
regarding neighbor discovery (although there are other
operational security concerns, as well).
I'd like to provide this as an example of those
concerns, without any additional commentary. :-)

I read the article and Tim Warnock on ipv6.org.au gave
a pretty good and very brief summary. Pasted here for
those that don't have time to read it. :-)
"large L2 domain + ipv6 windows privacy extensions + some
intel card bug + some mention of igmp snooping = multicast
flood w/ high switch/router cpu..."
Of course it's worth reading and there is a lot more to
the post...
