DNS Server Operators:
Does this reserved Special-Use Domain Name have any potential
impact on DNS server operators? If they try to configure their
authoritative DNS server as authoritative for this reserved name,
will compliant name server software reject it as invalid? Do DNS
server operators need to know about that and understand why?
Even if the name server software doesn't prevent them from using
this reserved name, are there other ways that it may not work as
expected, of which the DNS server operator should be aware?
DNS server operators SHOULD, if they are using private addresses,
configure their authoritative DNS servers to act as authoritative
for these names.
DNS server operators SHOULD, if they are using test names,
configure their authoritative DNS servers to act as authoritative
for test names.
DNS server operators SHOULD be aware that the effective RDATA for
localhost names is defined by protocol specification and cannot
be modified by local configuration.

DNS server operators SHOULD be aware that the effective RDATA for
"invalid" names is defined by protocol specification to be
nonexistent and cannot be modified by local configuration.
