Hi Tom,
The definition in RFC 1594 was far better.
A Fully Qualified Domain Name (FQDN) is a domain name that
includes all higher level domains relevant to the entity named.
If you think of the DNS as a tree-structure with each node having
its own label, a Fully Qualified Domain Name for a specific node
would be its label followed by the labels of all the other nodes
between it and the root of the tree. For example, for a host, a
FQDN would include the string that identifies the particular host,
plus all domains of which the host is a part up to and including
the top-level domain (the root domain is always null). For
example, atlas.arc.nasa.gov is a Fully Qualified Domain Name for
the host at 128.102.128.50. In addition, arc.nasa.gov is the FQDN
for the Ames Research Center (ARC) domain under nasa.gov.
Unfortunately, this definition has disappeared in the RFC 2664 that has
obsoleted RFC 1594.
After investigation, I have failed to find a correct reference for the
definition in IETF documentation... which is weird, isn't it?
As I said, this comment is a minor one and its applicability is broader than
the scope of the present draft. It is not intended to block its publication.
Regards,
Lionel
