Our authoritative name servers have had IPv6 addresses for some time now but until earlier today our glue records did not list the server’s AAAA addresses. Support for IPv6 on our authoritative name servers is now complete. However, it is worth noting that v6 requests account for <0.1% of our total authoritative DNS requests. Customer’s with their own registered name servers (you run your own DNS servers) that are IPv6 ready may submit requests to have their glue records manually updated to include their AAAA records. -Kelsey
