IPv6 Report 2020-06 for US Government and Military Domains

DNS Institute performs detailed audits of DNS domain names and nameservers for the US government, S&P Global Top 100 Banks, and Fortune 500 (US) companies. This analyzes for requirements for DNS registries, government mandates, and Internet specifications.

This is a report of IPv6-only DNS support for United States government and military domains. Of 1302 domains that worked with DNS (any combination of IPv4, IPv6, UDP, and TCP), 651 (50%) domains had at least one problem with their IPv6 delegation or resolution and up to 247 (19%) domains did not work at all for IPv6-only DNS. Akamai had 42 nameservers in this study with failures for 227 US government domain names. The General Services Administration had 72 domains with failures (from three nameservers). Six US Department of Defense Non-classified Internet Protocol Router Network nameservers didn't have AAAA addresses resulting in complete IPv6 failures for 71 .mil domains in this study. The National Institutes of Health had at least 18 domains with failures.

In August 2005, the United States government White House Office of Management and Budget (OMB) published a memorandum that all federal agencies networks must interface with IPv6 by June 2008. As of recently, that transition is still incomplete. A series of guidance documents highlighted that applications should be able to operate in IPv6-only modes with no less functionality available if were doing IPv4. Specifically for DNS, the client and servers are to be fully functional and required to support IPv6 address records and DNS queries over native IPv6.

RFC 3901 DNS IPv6 Transport Operational Guidelines recommends that all DNS zones should be served by at least one IPv4-reachable authoritative name server and there should be at least one IPv4 address for delegations. While it says "[t]his rules out DNS zones served only by IPv6-only authoritative name servers", later RFCs (like RFC 8305) state that queries should be sent over IPv6 first.

Even though the NIST guidelines recommend not getting cut off from DNS by disallowing IPv4-only, this study highlights the domains that don't have AAAA records for the delegated NS nameservers and those that don't have IPv6 nameservers answering for their domains. This study doesn't check for address records for the domains themselves, but focuses on the nameserver delegations leading to the domain and its SOA record. Below, this first lists several popular domains with IPv6 problems, the many domains with complete IPv6 failures, and then shows the lameness problems for all the domains that had at least one IPv6-related failure: nameservers names with failing AAAA lookups, nameservers returning SERVFAIL or REFUSED, and IPv6 nameservers which could not be reached.

Popular Domains with Partial or Complete IPv6 Failures

Sixty-five domains that partially failed for IPv6 are in the top 10,000 of the Tranco top sites ranking list (2020-06-15). Thirteen domains completely failed for IPv6 in the top 10,000 are marked with an asterisk (*).
