Hello Markus,

On Saturday December 30 2017 16:25, you wrote to Robert Wolfe:

Educated guess:

Comcast follows the example of the European daughters of Liberty Global:

New customers or customers that for some reason get a new modem/router are put on a DS-Lite connection. On request they are downgraded to an IPv4 only connection. Dual Stack is phased out and only available on high end bussiness accounts.

Here in The Netherlands the DSL and fiber providers that offer IPv6 still offer Dial Stack. The cable companies are going DS-Lite.


Cheers, Michiel
