NAME
       rdapper - a command-line RDAP client.

DESCRIPTION
       rdapper is a command-line client for the Registration Data Access
       Protocol (RDAP), the successor protocol to Whois (RFC 3912). RDAP is
       currently being developed by the WEIRDS IETF working group, and has not
       yet been finalized.

       This tool will send an RDAP query to an RDAP server over HTTP or HTTPS,
       parse the JSON response, and display it in human-readable form.

INSTALLING
       To install this program type the following commands in the source
       directory:

          perl Makefile.PL
          make
          make install

USAGE
           rdapper [OPTIONS] QUERY

OPTIONS
       --host=HOST (default: rdap.org)
           Specify the host to query. If not set, rdapper uses "rdap.org" (see
           below).

       --TYPE=TYPE
           Specify the type of object being queried. Possible values are:
           "domain", "entity" (also "contact"), "nameserver" (also "host"),
           "autnum" and "ip".  rdapper will detect IPv4 and IPv6 addresses and
           CIDR networks and AS numbers, and will fall back to domain queries
           for everything else.

       --follow
           Instructs rdapper to follow links to retrieve full entity
           information.

       --links
           Display URIs for referenced objects.

       --path=PATH
           Specify a JSONPath query. Any elements in the response which match
           this path will be printed in JSON format.

           See below for details of JSONPath.

       --tls
           Force use of TLS.

       --insecure
           Disable server certificate checking and hostname verification.

       --username=USERNAME
           Specify a username to be used with Basic Authentication.

       --password=PASSWORD
           Specify a password to be used with Basic Authentication.

           Note: if the initial request is redirected, authentication
           credentials will be sent in the subsequent request to the target
           server, so users should consider whether these credentials might be
           disclosed inappropriately.

       --cert=CERTIFICATE
           Specify a client SSL certificate to present to the server.

       --key=KEY
           Specify a private key matching the certificate given in "--cert".

       --keypass=PASSPHRASE
           Specify a passphrase to decrypt the private key given by "--key".

       --raw
           Causes rdapper to emit pretty-printed JSON rather than text output.

       --debug
           Causes rdapper to display the HTTP request and response rather than
           the text output.

       --lang=LANGUAGE
           Specify a language. This is sent to the server using the
           "Accept-Language" header. If unset, the language will be taken from
           your $LANG environment variable (or "en" if that is not defined).

       --encoding=ENCODING
           Specify an encoding. This is sent to the server using the
           "Accept-Encoding" header. If unset, the encoding will be taken from
           your $LANG environment variable (or "UTF-8" if that is not
           defined).

JSONPath
       You can use JSONPath to specify a subset of the complete response.
       JSONPath is an XPath-like syntax for querying JSON structures. The
       following are examples of JSONPath queries:

               $.handle                # the handle of an object
               $.nameServers[0].name   # the name of a domain's first nameserver
               $.entities[0].emails[0] # the first email address of an object's first entity
               $.nameServers..name     # the names of every nameserver

       For a full explanation of the available syntax, see the link below.

USE OF RDAP.ORG
       Unless instructed otherwise (via the "--host" argument), rdapper will
       send all queries to rdap.org: this server is an aggregator of RDAP
       services, and will provide an HTTP redirect to the appropriate service
       where available.
