Test your IPv6.

Spectrum support was able to activate the modem/router without a problem. The cable/internet are working properly, but noticed that IPv6 internet protocol was not working. Ran an IPv6 test on the internet and came back that we did not have connectivity, only IPv4 on all devices. Ping uses either ICMPv4 Echo or ICMPv6 Echo Request messages to verify IPv4-based or IPv6-based connectivity. Ping can parse both IPv4 and IPv6 address formats. If you specify a target host by name, the addresses returned by using Windows name resolution techniques can contain both IPv4 and IPv6 addresses—in which case, by default, an IPv6 This test will be skipped if no IPv6 addresses were found, or if your servers do not provide SSL connectivity on IPv4. IPv6 addresses for incoming mail servers Checks that the mail servers listed in your MX records have IPv6 addresses. If anyone has the capacity and willingness to run a test-ipv6.com mirror inside China (including the ICP license, or ICP备案 ), please contact jfesler@test-ipv6.com . Connectivity leaving China is spotty, and consequently affects the tests. IPv6 Test Cases. This Perl test script has over 200 test cases of valid and invalid IPv6 addresses. You can use them to test your own implementation. In addition, it has pointers to several other regular expressions that can be used for IPv6. Test jBoss port 8080 with curl. This scenario shows that connection is refused (probably because there’s no service running on that port). IMPORTANT: you would probably get a different message if firewall blocks the 8080 port. Connection refused is a clear sign that port is accessible, but nothing’s responding on it. IPv6 Connectivity There are a few more methods with IP version 6 for address allocation than what we had with IP version 4. With IP version 6, we will have manual assignment, just like IP version 4.

If your router permits you to log in, use "ping" or "ping6" and see if you can ping "ipv6.test-ipv6.com". Don't waste your time fixing computers until the router works! If you are using your Linux, BSD, Mac, or Windows box to "talk 6to4" specifically: Make sure your router is passing "protocol 41" to you.
