In order to use nslookup  host or gethostbyname   then the target s name will need to be registered with DNS or statically defined in the hosts file on the machine running your program  Yes  you could connect to the target with SSH or some other application and query it directly  but for a generic solution you ll need some sort of DNS entry for it
