I have no idea what my ISP assigned me, though quick searches of the TWC forums seem to mention a /56. But it seems my router is only giving me a /64 as well. Granted, I'm using the "Native" connection type, and also using DHCP-PD. If I disable either one of the two, I am able to input my own data and request different sized prefix lengths. Since I don't really see a reason at the moment to need 256 subnets for less than 20 devices.. I probably won't dive into it much further at this time.

 MV> You get that speed on both IPv4 and IPv6?

Looks like my IPv6 speed test is a little bit faster. 61.2mb/s (IPv4) vs. 62.5mb/s (IPv6). Not really much of a difference, but looks like I do indeed get that speed on both. This was also tested on ipv6-test.com/speedtest and the nearest testing location for me was in the UK.

I don't think I've ever even tried this. While my router has it's own IPv6 address, I can't seem to connect to the router's web config via IPv6 either.

I'm sure it will. But as long as the router handles dual stack, it's most likely not an issue. If "please.send.me.somewhere.cool" was a viable address, even that could be used to access your router inside your LAN.

Regards,
Nick
