That's why this query works. Wow! I am delighted that I've been able to get an answer to my question direct "from the horse's mouth" as we say... and on a Sunday even! So, um, THANK YOU for that. But please allow me a couple of follow-up questions also... It appears to me that the "a" root server _does not_ allow the zone transfer. My guess is that the operators of that server wished to prevent every impertinent fellow (like me) and his brother from all writing scripts which would run frequently and which would always suck copies of the root zone from the most obvious candidate, i.e. a.root-servers.net. Is that approximately correct? Or are the operators of the "a" server just less friendly/accomodating folks than you? ;-) Do 100% of the other (non-a) root zone servers support axfr for the root zone? (I only checked "b", "c", and your's, "k", but those all seem to do so.) Is the openness of your server (to root zone axfrs) a policy choice that I can rely on, i.e. that is likely to be in place for the forseeable future? I ask because I have indeed written a script which I will be running on the order of once per day, and which needs to be able to suck down a copy of the root zone. May I rely on this continuing to work for the forseeable future if I hardcode my little script with the name "k.root-servers.net"? Or is there a better choice for the long term?
