Given the amount of discussion this topic has generated, and the number of
ways I've seen the word used in the past (and, in fact, have used it myself
when speaking imprecisely), a discursive paragraph about common misuses
might be helpful. Like:
The term "glue" is sometimes incorrectly used to refer to
other resource records in a parent zone that are related to a
delegation, such as address records included with a referral
which are not strictly necessary due to the server's domain
name falling below the zone cut, the authoritative delegation
(NS), or the delegation signer (DS).
This could help newcomers to the DNS to understand what they're reading
when they encounter terms like "NS glue", but it still stakes out a clear
definition of the word.
