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
192.168.0.1or2001: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
--typeargument to explicitly tellrdapperthat you want to perform an entity query, .e.grdapper --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 causesrdapperto display the record of the correspondingin-addr.arpaorip6.arpadomain.--type=TYPE- explicitly set the object type.rdapperwill guess the type by pattern matching the value ofOBJECTbut you can override this by explicitly setting the--typeargument to one of :ip,autnum,domain,nameserver,entityorurl.If
--type=urlis used,rdapperwill directly fetch the specified URL and attempt to process it as an RDAP response. If the URL path ends with/helpthen 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=entityis used,OBJECTmust be a a string containing a "tagged" handle, such asABC123-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.
