I'm not sure if IPv6 is in use on any of my machines! Certainly not at
home because I'm behind a cheapish ADSL router which is most definitely
v4 only. However, at work our network is v6 aware locally (not much
traffic at the moment, but some). Shortly, our regional and national
networks will be v6 native, hence my concern about potential security
issues.

I strikes me that some people are saying there are security concerns
with IPv6 but no-one has pointed me to a specific example of a known
exploit or even vulnerability, and that is what is bothering me with
this whole discussion.

Regards,
Tony.
