Random #DNS fact of the day : 129 out of the 1465 domains in the root zone (roughly 8.8%) have a TXT record. Most of them (52, 40.6% of the records) are just : "Generation Time: <UNIX timestamp>" (eg. as. TXT)"
Some of them are more explicit (see cg. TXT or tm. TXT)
@afnic puts a crytpic message in its zone, surely the number of changes since last update (see fr. TXT, eg. "296 RRs processed [25/09/2023 13H10:42" please note the ugly date format "H" :P )
