Is that implementation specific? It doesn't seem to be the case with unbound. It probably works because the NS records are already provided by the .rs tld nameservers: # dig @f.nic.rs eurobank-direktna.rs ns [...] ;; QUESTION SECTION: ;eurobank-direktna.rs. IN NS ;; AUTHORITY SECTION: eurobank-direktna.rs. 3600 IN NS ns2.eurobank.rs. eurobank-direktna.rs. 3600 IN NS ns1.eurobank.rs. eurobank-direktna.rs. 3600 IN NS ns3.eurobank.rs. # dig @ns1.eurobank.rs eurobank-direktna.rs ns [...] ;; QUESTION SECTION: ;eurobank-direktna.rs. IN NS ;; ANSWER SECTION: eurobank-direktna.rs. 3600 IN NS bgdit01edns01.eurobank.rs. This is obviously wrong, but why should a resolver query @ns1.eurobank.rs for eurobank-direktna.rs nameservers as this information is already known. And it's not a subdomain that might be delegated to another nameserver.
