 dig command questions DNS 	

1)I am sharing internet through proxy server

what should put in the ip of the dns server tho use
dig command, whether i should put address of proxy
server or the address of dns server

dig @DNS_server host

and when i tried with dns server ip it says,
# dig @172.16.0.1 www.linuxquestions.org

; <<>> DiG 9.2.3rc2 <<>> @172.16.0.1
www.linuxquestions.org
;; global options: printcmd
;; connection timed out; no servers could be reached

and when i tried with proxy server ip it says same
thing as above.

#/etc/resolv.conf
nameserver 127.0.0.1
nameserver 192.168.1.2
nameserver 172.16.0.1


2)# nslookup www.linuxquestions.org
Note: nslookup is deprecated and may be removed from
future releases.
Consider using the `dig' or `host' programs instead.
Run nslookup with
the `-sil[ent]' option to prevent this message from
appearing.
;; connection timed out; no servers could be reached

how can i run nslookup command
