Big day for IPv6 - 1% native penetration

Wed Nov 21 20:54:34 UTC 2012

We have cable broadband operations using vendor M and we're a little gun-shy because that vendor has lagged the other two with IPv6 support, and when Comcast and TimeWarner began their production IPv6 rollouts on their CMTes it wasn't with vendor M.

This has partially been a vendor issue, at least for cable providers. 
Two of the major CMTS vendors (one starts with C, the other A) have had 
IPv6 related bugs in fairly recent code releases.    Both of the MSOs 
I've worked for have had to delay IPv6 deployment while those vendors 
get their waterfowl properly aligned.  I know we're still waiting for 
one vendor to get it straightened out.
