  • dig AAAA ns1.exampledomain.tld @tld.server ✅
  • dig -x 2001:db8::1 @tld.server
  • dig A ns1.exampledomain.tld @tld.server
  • ping ns1.exampledomain.tld

4. Which TLD listed below is authoritative for .com & .net IPv6 Glue?

  • A.GTLD-SERVERS.net ✅
  • a0.org.afilias-nst.info
  • ipv6.arpa
  • GDNS1.ULTRADNS.NET

8. Why does getting AAAA records for your nameservers in the corresponding TLD (top level domain) zone matter?

  • It enables entirely native IPv6 DNS queries and makes it possible for IPv6 only hosts to reach the nameservers for your domain, since they can’t use glue that is just an A record. ✅
  • It doesn’t. It’s too hard, so you shouldn’t bother.
