You haven't provided any information as to what you have tried so far.

Have you used 'ip name-server 1.2.3.4', where '1.2.3.4' is the IP address of
the same server you wish to query?

evil_homer(config)#ip name-server 195.92.195.222
evil_homer(config)#^Z
evil_homer#ping
Jan 29 20:01:38: %SYS-5-CONFIG_I: Configured from console by chris on
console
evil_homer#ping www.google.com
Translating "www.google.com"...domain server (212.50.160.100) [OK]

Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 66.249.93.104, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 36/36/36 ms
