Brink, I know that I don't have IPv6 connectivity at my house. What is the easiest way to know if it is the router, modem, or the ISP, assuming there is an easy way?

Hello Petey,

The easiest way to test is to use the Test Your IPv6 site. You could also check the documentation of the router and modem to see if they support IPv6 and how to set them up for that specific device.

Today is the day IPv6 finally goes live. For as long as there has been an Internet IPv4 has been synonymous with IP and nobody really stopped to think about which version of the protocol it was. But, IPv4 has outlived its usefulness.

Researchers saw the writing on the wall, and could predict based on the rate of growth for Internet use and IP-connected devices that IPv4 couldn’t last forever. IPv6 has been in development for nearly two decades. Now, the next generation protocol is ready to replace IPv4 and assume its place as the backbone of the Internet.

So, what exactly is IPv6 and what does it mean to you?

Thanks for the fast reply Brink. Using the IPv6 test site, it says that I have no IPv6 IP address and my DNS server has no IPv6 connectivity, so I assume it is an ISP issue. Also, I notice under Wireless Network Status on my computer, it says No Internet Connectivity, as opposed to no network access. Is it safe to assume from this that the router supports IPv6 and my ISP (Verizon DSL) does not? I'm mostly concerned with wether or not ther router would have to be replaced for IPv6 to work.

When will Comcast start rolling out IPV6? I used the Test Ipv6 site and it said that I do not have any ipv6 connectivity.

Most ISPs are not IPv6 ready yet. However, your router still may or may not support IPv6. What is the brand and model number of your router? We can look it up to make certain.

It is a Linksys WRT54G (I know, old). Also, after turning the router on and off, Test-IPv6.org says I have an IPv6 address but still the DNS server still has no IPv6 connectivity.

EDIT: My IPv6 connection seems to be through something called Teredo, which does not appear to be true IPv6 connectivity.

Sorry Petey,

That model doesn't support IPv6. However, you will still be able to view the usual IPv4 addresses of sites.

Ah, okay. Out of curiousity, where did you find that information at? I was looking on the linksys website and couldn't find where it said one way or the other.
