-       IPv6 once introduced new complexity into the resolution process,
-       such as following A6 chains and DNAME records, and simultaneous
-       lookup of IPv4 and IPv6 addresses.  Though most of the complexity was
-       then removed, these are hard or impossible

-       that is distinct from and simpler than the full DNS protocol.
