Re: [IPv6] IPv6 not implemented in my area yet?

I wouldn't really encourage the use of tunnels at this point, it will be soon enough that you'll have native IPv6. At this point, there is no advantage to running a tunnel unless you have some specific need for IPv6 only content.

OP: I believe you do need a modem that is marked IPv6 compatible on »mydeviceinfo.comcast.net/?s=i&so···1&sc=211

Few things:

1 - You do need a better modem, you have an older modem that doesn't support, or well ISPs don't support IPv6 on it so you'll need one from the list above.

2 - Your area needs to have it too which it could but since you have the wrong modem you'll never know

3 - I have that modem too and you can use Hurricane Electric if you want IPv6. You wont get 6to4 with that router though as it's not one of the supported options. No big deal IMO. 6rd is supported though IIRC.

So with all that said, wait till you find out if IPv6 is available in your area, or you can check it kinda by finding out your CMTS MAC address (within your modem logs). From then if you have a CISCO CMTS then you don't have IPv6 at all and be done. IF it's Arris then maybe - If so though you should in 90 days or something according to Comcast. So on that day with the right modem and with your router set to Automatic, you'll just get IPv6 oneday without even doing a thing.

You should upgrade the modem to at least a DOCSIS 3 model. Even though there is a spec via cable labs, I've yet to hear of any DOCSIS 2 users getting v6.

Heartily agree with this ! Tunnels add overhead.

Not sure what kind of overhead you are referring to. Here are my results using 6to4 tunnel. Anything faster would pretty much have to break the speed of light:

Test with IPv4 DNS record
ok (0.286s) using ipv4

Test with IPv6 DNS record
ok (0.298s) using ipv6

Test with Dual Stack DNS record
ok (0.215s) using ipv4

Test for Dual Stack DNS and large packet
ok (0.143s) using ipv4

Test IPv4 without DNS
ok (0.138s) using ipv4

Test IPv6 without DNS
ok (0.141s) using ipv6

Test IPv6 large packet
ok (2.427s) using ipv6

Test if your ISP's DNS server uses IPv6
ok (0.227s) using ipv4

Until IPv6 comes to town the HE tunnels are amazing. Latency soo low I have trouble believing it's a "tunnel".
