Reverse DNS not working for my IPv6 addresses - ZIP 78729

Reverse DNS is not working for my IPv6 addresses in Austin, TX 78729 - similar problem in this thread: http://forums.timewarnercable.com/t5/forums/v3_1/forumtopicpage/board-id/IPv6/thread-id/560

 

Neither assigned /128 nor PD /56 are working:

  • 2605:6000:ffc0:71:597f:2740:855d:6472/128
  • 2605:6000:ecc9::/56

As listed in that thread, I've also emailed phil.blum@twcable.com Spectrum-PhilB, Community Manager.
