Hi Dan, Assuming Comcast use plain Ethernet, I am certain they will send RAs with M=1. That said, you *are* allowed to kick off DHCPv6 before receiving an RA in order to speed up the activation process. However, if you do, you need to always request an IA_NA address (in other words behave as if you're expecting an RA with M=1). Microsoft Windows does this. Without an RA, however, you won't get on the internet, as RAs are the only way to discover the default router(s). So waiting for an RA before starting DHCPv6 (like currently NM does) is perfectly reasonable too, perhaps even more so at this point in time, where most networks have neither RAs or DHCPv6 service.
