  Oh yes, the IPV6 automatic Teredo tunnel ...  I was curious, so I poked
around for some articles on this.   I found a good one.   The default Vista
IPV6 configuration is a Zero-intervention migration to IPV6.

  The "Disabling IPV6" section at the bottom gives some great tips on
disabling some of the automatic stuff that aren't needed.

   I'll bet that 10 years from now, 80% of companies will still be 100%
IPV4 (inside and out), despite more and more equipment including better and
better support for IPV6.
