A lot of things in the DNS can be thought as BIND-specific if it were documented after implementation in BIND. :) Your initial comment was "we should not focus too much specificly on how BIND handles things with $ORIGIN"; it is how implementations that parse master files handle $ORIGIN. It is not BIND-specific. I tried to look up when $ORIGIN got introduced in BIND. :) On ftp.isc.org, I could find versions starting from 4.8, but that was newer than 1987 when RFC 1035 was published. So I tried finding it in 4.3BSD source code trees; the only one I could find predating 1987 (if the sccsid can be believed) is here: https://www.tuhs.org/cgi-bin/utree.pl?file=4.3BSD-UWisc/src/etc/bind/named/db_load.c which implemented $ORIGIN. (We on this list are fortunate to have Paul Vixie on it and he may be able to offer more history.) Some older docs on BIND: https://www2.eecs.berkeley.edu/Pubs/TechRpts/1984/CSD-84-182.pdf https://www2.eecs.berkeley.edu/Pubs/TechRpts/1984/CSD-84-177.pdf That Berkeley tech reports archive is a treasure trove. All sorts of cool things came from there. Mukund
