hi, i tried to set up ipv6 with the CenturyLink guide, but it did not work.

@gnad 

What do you mean by 'did not work'?

On Windows? Open a CMD prompt and enter IPCONFIG /ALL. Do you see IPv6 addresses?

Partial of my IPCONFIG output:

==========

 Default Gateway . . . . . . . . . : fe80::52d4:f7ff:fe68:
                                     192.168.0.1
 DHCP Server . . . . . . . . . . . : 192.168.0.1
 DHCPv6 IAID . . . . . . . . . . . : 612384605
 DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-1D-04-98-
 DNS Servers . . . . . . . . . . . : 2001:4860:4860::8888
                                     2001:4860:4860::8844
                                     192.168.0.1
                                     192.168.0.1

===========

I have Charter and my TP-Link Archer A20 doesn't show the DNS addresses (I use Dynamic IP (SLAAC/DHCPv6) as the type). It does show my IPv6 Address though (verified by IPCONFIG above). The 2 IPv6 DNS's above are Google's, which my A20 supplies when the ISP doesn't respond for the IPv6 DNS addresses. Spectrum/Charter uses 'Dual Stacked' IPv4 DNS's.

You might have the same situation with CenturyLink. One way to tell is use PING command. Like this:

=================

C:\>ping www.cnn.com

Pinging turner-tls.map.fastly.net [2a04:4e42::323] with 32 bytes of data:

Ping statistics for 2a04:4e42::323:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 19ms, Maximum = 20ms, Average = 19ms

=================

In the above, IPv6 addressing is use if there is a comparable site, like CNN uses.

@ArcherC8 ok, i will do that later, here is my test result from test-ipv6.com: http://test-ipv6.com/?ip4=174.21.104.254&ip6=2002:ae15:68fe:1:cd95:491a:3c0d:3d84&a=ok,96,4&aaaa=ok,111,6&ds=ok,92,4&ipv4=ok,169,4&ipv6=ok,160,6&v6mtu=timeout,16987&v6ns=ok,176,4&dsmtu=ok,184,4

@IrvSp when I do that, it just uses ipv4, and when I do the ipv6 address, it times out. I will power cycle the router as suggested by @ArcherC8. 

@gnad 

From your link, you appear to have an IPv6 IP WAN Address:

================

Your IPv6 address on the public Internet appears to be 2002:ae15:68fe:1:cd95:491a:3c0d:3d84
Your IPv6 service appears to be: 6to4

================

Also there appears to be an ISP problem with LARGE Packets:

================

=========================================

You are doing 'tunneling' (https://en.wikipedia.org/wiki/6to4).

In your Manual, https://static.tp-link.com/2020/202011/20201116/1910012697_Archer%20AX6000%201.0_UG_REV1.1.0.pdf, look at page 19, How to setup IPv6. Do you have it set to Tunneling, Page 21, step 4? If so, do step 5 on the next page. Give that a try. That is what I'm using.

@ArcherC8 whatismyip.com was showing my ipv4 and ipv6 addresses before, but the ipv4 address was above the ipv6 address.

You should be getting 10/10 from the test from test.ipv6.com if all is working okay.

@ArcherC8,

The above link is wrong. Should be https://ipv6-test.com/

In my case, I can't reach the full count, ISP part of the problem:

The Router I have, an Archer A20 doesn't allow changing the firewall for IPv6 for instance.
