+.Sh NAME
+.Nm whois

+.Sh SYNOPSIS
+.Nm whois
+.Op Fl AadgIilmPQRr
+.Oo
+.Fl c Ar country-code | Fl h Ar host
+.Oc
+.Op Fl p Ar port
+.Ar name ...
+.Sh DESCRIPTION
+The
+.Nm
+utility looks up records in the databases maintained by several
+Network Information Centers
+.Pq Tn NICs .
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl A
+Use the Asia/Pacific Network Information Center
+.Pq Tn APNIC
+database.
+It contains network numbers used in East Asia, Australia,
+New Zealand, and the Pacific islands.
+.It Fl a
+Use the American Registry for Internet Numbers
+.Pq Tn ARIN
+database.
+It contains network numbers used in those parts of the world
+covered neither by
+.Tn AfriNIC ,
+.Tn APNIC ,
+.Tn LACNIC ,
+nor by
+.Tn RIPE .
+.Pp
+(Hint: All point of contact handles in the
+.Tn ARIN
+whois database end with
+.Qq Li -ARIN . )
+.It Fl c Ar country-code
+This is the equivalent of using the
+.Fl h
+option with an argument of
+.Qq Ar country-code Ns Li .whois-servers.net .
+.It Fl d
+Use the US Department of Defense database.
+It contains points of contact for subdomains of
+.Tn \&.MIL .
+.It Fl g
+Use the US non-military federal government database, which contains points of
+contact for subdomains of
+.Tn \&.GOV .
+.It Fl h Ar host
+Use the specified host instead of the default NIC
+(whois.crsnic.net).
+Either a host name or an IP address may be specified.
+.Pp
+By default
+.Nm
+constructs the name of a whois server to use from the top-level domain
+.Pq Tn TLD
+of the supplied (single) argument.
+For newer generic domains (gTLDs), a lookup for whois.nic.tld is attempted.
+For other TLDs, or if this lookup fails,
+.Qq Li .whois-servers.net
+is appended to the TLD.
+This effectively allows a suitable whois server to be selected
+automatically for a large number of
+.Tn TLDs .
+.Pp
+In the event that an IP
+address is specified, the whois server will default to the American
+Registry for Internet Numbers
+.Pq Tn ARIN .
+If a query to
+.Tn ARIN
+references
+.Tn APNIC , LACNIC ,
+or
+.Tn RIPE ,
+that server will be queried also, provided that the
+.Fl Q
+option is not specified.
+.Pp
+If the query is not a domain name or IP address,
+.Nm
+will fall back to
+.Pa whois.crsnic.net .
+.It Fl I
+Use the Internet Assigned Numbers Authority
+.Pq whois.iana.org
+root zone database.
+It contains information about top-level domains.
+.It Fl i
+Use the Network Solutions Registry for Internet Numbers
+.Pq Tn whois.networksolutions.com
+database.
+Historically, it contained network numbers and domain contact information
+for most of
+.Tn \&.COM ,
+.Tn \&.NET ,
+.Tn \&.ORG
+and
+.Tn \&.EDU
+domains.
+However, the registration of these domains is now done by a number of
+independent and competing registrars and this database holds no information
+on the domains registered by organizations other than Network Solutions, Inc.
+Also, note that the
+.Tn InterNIC
+database
+.Pq Pa whois.internic.net
+is no longer handled by Network Solutions, Inc.
+For details, see
+.Lk http://www.internic.net/ .
+.Pp
+(Hint: Contact information, identified by the term
+.Em handle ,
+can be looked up by prefixing
+.Qq Li \&!
+or
+.Qq Li handle\ \&
+to the
+.Tn NIC
+handle in the query.)
+.It Fl l
+Use the Latin American and Caribbean IP address Regional Registry
+.Pq Tn LACNIC
+database.
+It contains network numbers used in much of Latin America and the
+Caribbean.
+.It Fl m
+Use the Route Arbiter Database
+.Pq Tn RADB
+database.
+It contains route policy specifications for a large
+number of operators' networks.
+.It Fl P
+Use the PeeringDB database of AS numbers.
+It contains details about presence at internet peering points
+for many network operators.
+.It Fl p Ar port
+Connect to the whois server on
+.Ar port .
+If this option is not specified,
+.Nm
+defaults to the
+.Dq whois
+port listed in
+.Pa /etc/services
+(port 43).
+.It Fl Q
+Do a quick lookup.
+This means that
+.Nm
+will not attempt to lookup the name in the authoritative whois
+server (if one is listed) nor will it contact InterNic if a lookup
+fails.
+This flag has no effect when combined with any other flag.
+.It Fl R
+Use the Russia Network Information Center
+.Pq Tn RIPN
+database.
+It contains network numbers and domain contact information
+for subdomains of
+.Tn \&.RU .
+This option is deprecated; use the
+.Fl c
+option with an argument of
+.Qq Li RU
+instead.
+.It Fl r
+Use the Reseaux IP Europeens
+.Pq Tn RIPE
+database.
+It contains network numbers and domain contact information for Europe.
+.El
+.Pp
+The default action, unless directed otherwise with a special
+.Ar name ,
+is to do a very broad search, looking for matches to
+.Ar name
+in all types of records and most fields (name, nicknames, hostname, net
+address, etc.) in the database.
+For more information as to what
+.Ar name
+operands have special meaning, and how to guide the search, use
+the special name
+.Dq help .
+.Ss Special cases
+Queries beginning with an exclamation point
+.Ql \&!
+are assumed to be
+.Tn NSI
+contact handles.
+Unless a host or domain is specified on the command line,
+.Pq whois.networksolutions.com
+will be used as the
+.Nm
+database.
+.Pp
+Similarly, queries beginning with
+.Dq COCO-
+are assumed to be
+.Tn CORE
+contact handles.
+Unless a host or domain is specified on the command line,
+.Pq whois.corenic.net
+will be used as the
+.Nm
+database.
+.Sh EXAMPLES
+Most types of data, such as domain names and
+.Tn IP
+addresses, can be used as arguments to
+.Nm
+without any options, and
+.Nm
+will choose the correct whois server to query.
+Some exceptions, where
+.Nm
+will not be able to handle data correctly, are detailed below.
+.Pp
+To obtain contact information about an
+administrator located in the Russian
+.Tn TLD
+domain
+.Qq Li RU ,
+use the
+.Fl c
+option as shown in the following example, where
+.Ar CONTACT-ID
+is substituted with the actual contact identifier.
+.Pp
+.Dl "whois -c RU CONTACT-ID"
+.Pp
+(Note: This example is specific to the
+.Tn TLD
+.Qq Li RU ,
+but other
+.Tn TLDs
+can be queried by using a similar syntax.)
+.Pp
+The following example demonstrates how to query
+a whois server using a non-standard port, where
+.Dq Li query-data
+is the query to be sent to
+.Dq Li whois.example.com
+on port
+.Dq Li rwhois
+(written numerically as 4321).
+.Pp
+.Dl "whois -h whois.example.com -p rwhois query-data"
