i object to the term "suffix", which sounds like a CP/M "file
extension", like TXT in "FOOBAR.TXT", and is actually meant and used
that way, by people who don't realize that "FOOBAR.TXT" in DNS is more
closely aligned with "OTHERNAME.TXT" than it is with "FOOBAR.COM". in
other words, the right-to-left precedence is deliberately obscured by
the wrong-think term "suffix".

i suggest that we invent rather than import. i like "DMD =
Delegation-Mostly Domain". this allows for not just infrastructure
namespaces like IP6.INT (for which delegations might not be on the first
sublabel, and the delegations are often same-organization or other-DMD
organizations) and also for new invented terms like "Public DMD" to
describe domains like CO.UK (or COM) for which the delegation points are
on the first sublabel and nearly always accompany an administrative
boundary (so, different-organization below the cut.)
