$ dig ae ns @localhost
;; omitting
;; ANSWER SECTION:
ae. 3600 IN NS ns2.aedns.ae.
ae. 3600 IN NS ns4.apnic.net.
ae. 3600 IN NS nsext-pch.aedns.ae.
ae. 3600 IN NS ns1.aedns.ae.
;; Query time: 152 msec
$ dig art ns @localhost
;; omitting
;; ANSWER SECTION:
art. 164969 IN NS b.nic.art.
art. 164969 IN NS c.nic.art.
art. 164969 IN NS a.nic.art.
