nslookup
A Unix utility 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.
