A Unix utility by Andrew Cherenson for querying Internetdomain 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. . (1994-10-27)
