at IETF48 zeroconf WG and dnsext WG, I heard some comment on making
distinction between full qualified domain name (which is on the DNS
database), and hostname (which is configured onto each of the host,
and do not necessarily the same as FQDN). Not sure if it has wide
concensus, but it made some sense to me.
- we look up FQDN through DNS database
- we look up hostname through /etc/hosts
(i'm not sure if it is really correct)
- gethostname(3) returns hostname, not FQDN
it is kind of confusing, but this gave me a way to understand the
current situation. if we are okay with the distinction,
we may be able to state the following:
- if we are to lookup some name via ICMPv6 name lookup, it would
be hostname, not FQDN.
we need to update name-lookup draft again, though.
of course, the above distinction could be very wrong. but then,
how should we understand the current situation with gethostname(3)?
