That would be "dig @localhost" which will only return something if you are
running a DNS server locally.

This is the response on a machine *not* running DNS:

-bash-2.05b$ dig @localhost

; <<>> DiG 8.3 <<>> @localhost
; (2 servers found)
;; res options: init recurs defnam dnsrch
;; res_nsend to server localhost  ::1: Connection refused


This one is:

hydra$ dig @localhost

; <<>> DiG 8.3 <<>> @localhost
; (1 server found)
;; res options: init recurs defnam dnsrch
