SYNOPSIS

General form:

rdapper [OPTIONS] OBJECT

Examples:

rdapper example.com

rdapper --tld foo

rdapper 192.168.0.1

rdapper https://rdap.org/domain/example.com

rdapper --search "exampl*.com"

DESCRIPTION

rdapper is a simple RDAP client. It uses Net::RDAP to retrieve data about internet resources (domain names, IP addresses, and autonymous systems) and outputs the information in a human-readable format. If you want to consume this data in your own program you should use Net::RDAP directly.

OPTIONS

You can pass any internet resource as an argument; this may be:

• a "forward" domain name such as example.com;
• a top-level domain such as com;
• a IPv4 or IPv6 address or CIDR prefix, such as 192.168.0.1 or 2001:DB8::/32;
• an Autonymous System Number such as AS65536.
• a "reverse" domain name such as 168.192.in-addr.arpa;
• the URL of an RDAP resource such as https://example.com/rdap/domain/example.com.
• the "tagged" handle of an entity, such as an LIR, registrar, or domain admin/tech contact. Because these handles are difficult to distinguish from domain names, you must use the --type argument to explicitly tell rdapper that you want to perform an entity query, .e.g rdapper --type=entity ABC123-EXAMPLE.

rdapper also implements limited support for in-bailiwick nameservers, but you must use the --nameserver argument to disambiguate from domain names. The RDAP server of the parent domain's registry will be queried.

ARGUMENTS

• --registry - display the registry record only (the default).
• --registrar - follow referral to the registrar's RDAP record (if any) which will be displayed instead of the registry record. Cannot be used with --registry.
• --both - display both the registry and (if any) registrar RDAP records (implies --registrar).
• --reverse - if you provide an IP address or CIDR prefix, then this option causes rdapper to display the record of the corresponding in-addr.arpa or ip6.arpa domain.
• --type=TYPE - explicitly set the object type. rdapper will guess the type by pattern matching the value of OBJECT but you can override this by explicitly setting the --type argument to one of : ip, autnum, domain, nameserver, entity or url.
  • If --type=url is used, rdapper will directly fetch the specified URL and attempt to process it as an RDAP response. If the URL path ends with /help then the response will be treated as a "help" query response (if you want to see the record for the .help TLD, use --type=tld help).
  • If --type=entity is used, OBJECT must be a a string containing a "tagged" handle, such as ABC123-EXAMPLE, as per RFC 8521.
• --$TYPE - alias for --type=$TYPE. eg --domain, --autnum, etc.
• --search - perform a search.
• --help - display help message.
• --version - display package and version.
• --raw - print the raw JSON rather than parsing it.
• --short - omit remarks, notices, links and redactions.
• --bypass-cache - disable local cache of RDAP objects.
• --auth=USER:PASS - HTTP Basic Authentication credentials to be used when accessing the specified resource. This option SHOULD NOT be used unless you explicitly specify a URL, otherwise your credentials may be sent to servers you aren't expecting them to.
• --nocolor - disable ANSI colors in the formatted output.
• --debug -run in debugging mode.

RDAP Search

Some RDAP servers support the ability to perform simple substring searches. You can use the --search option to enable this functionality.

When the --search option is used, OBJECT will be used as a search term. If it contains no dots (e.g. exampl*), then rdapper will send a search query for exampl* to all known RDAP servers. If it contains one or more dots (e.g. exampl*.com), it will send the search query to the RDAP server for the specified TLD (if any).

Any errors observed will be printed to STDERR; any search results will be printed to STDOUT.

As of writing, search is only available for domain names.
