A 1.2.3.4 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.] -Cathy
