Re: [Business] IPv6 Availability

said by ropeguru:

So, what is the status of IPv6 for business customers at this point?

The status is that if you are a business class customer with a dynamic IP account, and you are using a standard cable modem, or an SMCD3G-CCR in bridge mode (I don't know about the new Netgear gateway), and if you are connected to an Arris CMTS, you should get native IPv4/IPv6 connectivity.

The above examples are from a Windows XP SP3 workstation behind a D-Link DIR655 and Motorola SB6121 (I have also tested the SMCD3G-CCR in bridge mode in combination with a Netgear WNR1000v2).

Here is the netsh IPv6 information from my Windows server. Note that it does not show the "Temporary" IPv6 address because it does not use DHCP for its LAN interface (I have IPv6 disabled on its WAN interface because otherwise I would have problems with dual IPv6 gateways):
