  nslookup
  
     <networking> A Unix utility program, originally by Andrew
     Cherenson, for querying Internet domain name servers.  The
     basic use is to find the Internet address corresponding to a
     given hostname (or vice versa).  By changing the query type
     (e.g. "set type=CNAME") other types of information can be
     obtained including CNAME - the canonical name for an alias;
     HINFO - the host CPU and operating system type; MINFO -
     mailbox or mail list information; MX - mail exchanger
     information; NS - the name server for the named zone; PTR -
     the hostname if the query is an Internet address, otherwise
     the pointer to other information; SOA the domain's
     start-of-authority information; TXT - text information; UINFO
     - user information; WKS - supported well-known services.
     Other types (ANY, AXFR, MB, MD, MF, NULL) are described in
     RFC 1035.
