Um, as the original poster, I WANT IPv6.  Not make IPv4 lookups faster 
by ignoring AAAA records.

Further testing has IPv6 working just fine.  Thing is when I enable the 
HIP API intercepts, FIrefox does not work.  Like they are doing 
something 'non-standard' with the regualr TCP socket API so that HIP 
can't slide in there.  I tried disabling a number of options, thinking 
it might be some security setting, but if it is, I have not found it.
