I cleaned it up a bit and put it on GitHub: https://github.com/shane-kerr/tldIPv6 In the README.md: "Next it goes through each TLD and does an NS lookup to get the authoritative list of name servers. It then tries each name server returned until it finds one with an AAAA record. If none of the name servers for a TLD have an AAAA record, then it is reported as not supporting IPv6." It wouldn't be too difficult to add checks to see that IPv6 works for at least one of the AAAA returned, but I was mostly just looking to see if each TLD is trying to provide IPv6, not how good of a job they are doing at it (although the results file does log TLD that fail to resolve at all, but that's a side effect of the process). :) Cheers, -- Shane _______________________________________________ DNSOP mailing list DNSOP@ietf.org https://www.ietf.org/mailman/listinfo/dnsop
