If you read CableLabs’ most recent modem certification report (and really, why wouldn’t you?) you’ll notice that more and more of the hardware certified is IPv6-compliant. In fact, in the last two cert waves, all of the modems certified are listed as supporting the newer protocol.
Depending on which reports you read, we’re on a course to run out of IPv4 addresses some time in the next two to twelve months. This likely won’t have a major effect on consumers, but ISPs have had to get aggressive about managing the transition, and that includes making sure modem manufacturers are supporting the switch. Luckily, the migration to DOCSIS 3.0 created a window for IPv6 upgrades as well. It’s nice when the timing works out.
The most recent CableLabs certification wave, CW 79, included four new D3 modems. Among them- the Motorola SVG7540 voice gateway. In addition to being IPv6 compliant, the SVG7540 was certified for DOCSIS 1.0, 2.0, and 3.0, as well as PacketCable 1.0 and 1.5.
