 is_index_page  used to identify if we're showing index page  Do I ever hate the ways that browsers break things with javascript disabled. Can't even count on noscript tags. ! noscript display: none; P score0 JavaScript Required This site requires JavaScript, as well as the ability to pull in cross-site scripts, in order to perform the testing. If this message does not go away, it means that JavaScript has been disabled, either by a plugin or extension in your browser, or by explicit browser setting. score1 Do you use NoScript? 
   If you use this Firefox add-on, you'll need to "Temporarily allow all this page". You will need to do this  B twice  for everything to work. Alternately, disable NoScript entirely until you are done with this site. You can opt instead to view the  simple_test.html simple test , which will give you a quick pass/fail for IPv4, IPv4+IPv6, and IPv6. It will however offer little diagnostic information.

            Fetches an object that has just an A record in DNS. This is expected to use IPv4. IPv6-only users might still reach this, if their provider has employed a NAT64/DNS64 or proxy solution.
           
            Test with IPv6 DNS record
           test_aaaa results_aaaa http://ipv6.test-ipv6.cz/ip/?callback=?&testdomain=test-ipv6.cz&testname=test_aaaa http://ipv6.test-ipv6.cz/ip/?callback=?  detail_aaaa 
            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
           test_ds results_ds http://ds.test-ipv6.cz/ip/?callback=?&testdomain=test-ipv6.cz&testname=test_ds http://ds.test-ipv6.cz/ip/?callback=?  detail_ds 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). If this test fails or times out, you can expect major problems as publishers start offering their sites on IPv6. 
             Test for Dual Stack DNS and large packet
           test_dsmtu results_dsmtu http://ds.test-ipv6.cz/ip/?callback=?&size=1600&fill=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx&testdomain=test-ipv6.cz&testname=test_dsmtu http://ds.test-ipv6.cz/ip/?callback=?&size=1600&fill=xxx...xxx  detail_dsmtu 
            Validates that you can connect to a dual-stack server (like the ds test); and that you can send/receive large packets on that connection. If this test times out for any reason, it indicates trouble for World IPv6 Day.
           
            Test IPv6 large packet
           test_v6mtu results_v6mtu http://mtu1280.test-ipv6.cz/ip/?callback=?&size=1600&fill=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx&testdomain=test-ipv6.cz&testname=test_v6mtu http://mtu1280.test-ipv6.cz/ip/?callback=?&size=1600&fill=xxx...xxx  detail_v6mtu 
            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
           test_v6ns results_v6ns http://ds.v6ns.test-ipv6.cz/ip/?callback=?&testdomain=test-ipv6.cz&testname=test_v6ns http://ds.v6ns.test-ipv6.cz/ip/?callback=?  
           (This is bonus credit)
           detail_v6ns 
            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
           test_asn4 results_asn4 http://ipv4.lookup.test-ipv6.com/ip/?callback=?&asn=1&testdomain=test-ipv6.cz&testname=test_asn4 http://ipv4.lookup.test-ipv6.com/ip/?callback=?&asn=1  detail_asn4 
            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
           test_asn6 results_asn6 http://ipv6.lookup.test-ipv6.com/ip/?callback=?&asn=1&testdomain=test-ipv6.cz&testname=test_asn6 http://ipv6.lookup.test-ipv6.com/ip/?callback=?&asn=1  detail_asn6 
            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.
           
            Test for buggy DNS
           test_buggydns1 results_buggydns1 http://buggydns1.test-ipv6.cz/images-nc/bg.gif?&testdomain=test-ipv6.cz&testname=test_buggydns1 http://buggydns1.test-ipv6.cz/images-nc/bg.gif  detail_buggydns1 
            Queries for a malformed AAAA record. Some routers mishandle these as "A" records, and only keep the first 32 bits. We want this test to fail to connect.

} debug_eof tab_sites other_sites answer Because you have IPv6 , we've added this tab to show you whether or not you can reach other IPv6 web sites on the Internet. Consider notifying your ISP, if there are sites that show up as broken. If you are the ISP, you can click the Info link to see what test URLs are being used.
   Hint : Columns are sortable (click the first row);  GIGO.test_sites(2); return false; click here  to re-check reachability from where you are to those mirrors.
     sitestablediv (generated by javascript)    GIGO.test_contents(2);  It is real easy to get added to this list for basic checks. Just provide two image URLs (one IPv4-only; one IPv6-only), to Jason Fesler <jfesler@gigo.com>. Also send your general web site address and organization name.
     
    Full mirrors are welcomed and appreciated, whether public or private. Please see  https://github.com/falling-sky/source/wiki the wiki  for details.
