m257: Ne znam šta si ti gledao ali radi:
To je cache na DNS-u koji koristis za name resolving - kod tebe ili tvog provajdera. Potrebno je da prodje jos par sati do par dana dok istekne TTL svih RR koji se zavrsavaju na .yu.
A inace, izgleda da je brisanje definitivno, jer NS query upucen ka primarnom serveru za .yu (ns1.nic.yu) za second-level domene (.ac.yu, .co.yu itd.) daje NXDOMAIN, ANSWER: 0. U normalnim okolnostima treba da dobijes NOERROR, ANSWER: n (n > 0) i spisak nameservera.
Primer - obrisan domen:
$ dig @ns1.nic.yu NS ac.yu
; <<>> DiG 9.5.1b1 <<>> @ns1.nic.yu NS ac.yu
; (1 server found)
;; global options: printcmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 42522
;; flags: qr aa rd; QUERY: 1, ANSWER: 0, AUTHORITY: 1, ADDITIONAL: 0
;; WARNING: recursion requested but not available

Funkcionalan domen:
$ dig @ns1.nic.yu NS ac.rs

Evo i jos malo primera:
$ gawk '{ print "dig @ns1.nic.yu NS "$1" | grep status:" }' | sh
ac.yu
co.yu
org.yu
edu.yu
eunet.yu
gov.yu
<Ctrl-D>

Uporedi to sa:
$ gawk '{ print "dig @ns1.nic.yu NS "$1" | grep status:" }' | sh
ac.rs
co.rs
org.rs
edu.rs
eunet.rs
gov.rs
