I'm trying to nail down some terminology for doc purposes.
The issue: most resources on the net freely describe a fully-qualified domian name ('FQDN') as to exclude the root domain; i.e, they exclude the trailing dot as mandated by some RFCs such as RFC 1535:
RFC 1535 is Informational. It has no status to mandate anything.
http://www.ietf.org/rfc/rfc1535.txt
An absolute "rooted" FQDN is of the format {name}{.} A non "rooted" domain name is of the format {name}
I'm trying to come up with some human-facing terminology that names these two forms:
"a.b.c." "a.b.c"
Many resources on the net use the term 'rooted domain name' for the former, but they're collectively ambigious about what the other form should be called.
Does anyone here have any solid advice, or can point me to a resource that would call out useful conventions?
This was all fueled by Microsoft's client code apparently stripping the root domain from PTR record results; I'm separately trying to track down why that's occuring...
RFC 952 as modified by RFC 1123 describe the legal syntax of a hostname. There is no trailing period.
