Test with IPv6 DNS record

 Test with IPv6 DNS record


ok (0.223s) using ipv6


https://ipv6.test-ipv6-vm3.comcast.net/ip/?callback=?


Fetches an object that has just an AAAA record in DNS. This is expected to use IPv6. Users not yet on the IPv6 Internet are likely to see this fail. As long as it fails quickly, it will be OK - for now.

Test with Dual Stack DNS record


ok (0.187s) using ipv6


https://ds.test-ipv6-vm3.comcast.net/ip/?callback=?


This is the most important test. This verifies your browser can connect to a site that has both IPv4 and IPv6 records published. IPv4 only hosts should connect fine (using IPv4).

Test IPv6 large packet


ok (0.184s) using ipv6


https://mtu1280.test-ipv6-vm3.comcast.net/ip/?callback=?&size=1600&fill=xxx...xxx


Validates that IPv6 requests with large packets work. If this test times out, but other IPv6 tests work, it suggests that there may be PMTUD issues; possibly involving IP tunnels. Double check to make sure that ICMPv6 Type 2 ("Packet Too Big") messages are not filtered by your firewall.

Test if your ISP's DNS server uses IPv6


ok (0.189s) using ipv6


https://ds.v6ns.test-ipv6-vm3.comcast.net/ip/?callback=?


(This is bonus credit)


This is a test of your ISP's resolver (instead of a test of your host). If this test passes, your DNS server (often run by your ISP) is capable of reaching IPV6-only DNS authoritative servers on the Internet. This is not critical (at this time) for you to reach sites via IPv6.

Find IPv4 Service Provider


ok (0.130s) using ipv4 ASN 7922


https://ipv4.lookup.test-ipv6.com/ip/?callback=?&asn=1


Attempts to identify what Internet Service Provider you use for IPv4. This may be different from the marketing name you see in your local market; or may reflect a previous company name. The name shown reflects how it is known in the network operator community

Find IPv6 Service Provider


ok (0.178s) using ipv6 ASN 7922


https://ipv6.lookup.test-ipv6.com/ip/?callback=?&asn=1


Attempts to identify what Internet Service Provider you use for IPv6. When the IPv4 name and the IPv6 name don't match, it may suggest that you're using a tunnel; or some form of third party provider for IPv6.
