rdapper - a simple console-based RDAP client.
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.
rdapper was originally conceived as a full RDAP client (back
when the RDAP specification was still in draft form) but is now
just a very thin front-end to Net::RDAP.
You can pass any internet resource as an argument; this may be:
- a "forward" domain name such as
- a "reverse" domain name such as
- a IPv4 or IPv6 address or CIDR prefix, such as
- an Autonymous System Number such as
- the URL of an RDAP resource such as
- 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 tell
rdapperthat you want to perform an entity query, .e.g
rdapper --type=entity ABC123-EXAMPLE.
--type=TYPE- explicitly set the object type.
rdapperwill guess the type by pattern matching the value of
OBJECTbut you can override this by explicitly setting the
--typeargument to one of :
rdapperwill directly fetch the specified URL and attempt to process it as an RDAP response.
OBJECTmust be a a string containing a "tagged" handle, such as
ABC123-EXAMPLE, as per RFC 8521.
--help- display help message.
--debug- enable Net::RDAP debug mode.
--short- omit remarks, notices, and links. Implies
--expand- attempt to "expand" truncated entity objects.
--bypass-cache- disable local cache of RDAP objects.
--auth=USER:PASS- HTTP Basic Authentication credentials to be used when accessing the specified resource.
--nopager- by default,
rdapperwill pass its output to

--raw- output raw JSON response (implies
Assuming you have
cpan installed, installing
rdapper should be
as simple as running this command:
sudo cpan -i rdapper
Otherwise, you can manually install
rdapper by running
perl Makefile.PL make sudo make install
You may need to manually install one or more of the dependencies
listed below, if they are not already installed, using
your operating system vendor's packages.
rdapper uses the following modules, some of which may already be
