Yes, I understand what a glue record is, but I don't see the likelihood of
ICANN/IANA creating nameservers in the in-addr.arpa domain. At least, to
date, it has not happened that I am aware. So, unless IANA does this, any
nameservers delegated in the in-addr.arpa zone would not require glue A
records. Theoretically possible? Yes. Rare? That implies that it happens.
In the meantime, I was wondering what a realistic example would be. [Not
trying to be argumentative, just covering the bases.]
