Tutorials: How to Query the RADB
The RADB whois server provides information collected from all the
registries that form part of the Internet Routing Registry.
These collected registries provide information on most of
the networks and ASs routed in the Internet today.
The query server is easy to use. For example, the following command
queries the RADB RPSL database for information about a network with the
address 128.223.0.0/16 . (The -h parameter tells the whois client on your
machine that you want to talk to the IRRd whois server):
whois -h whois.radb.net 128.223.0.0/16
The output includes an RADB "Route object" containing information about
the network:
route: 128.223.0.0/16

(This example is taken from RFC
2650, "Using RPSL in Practice.")
You can also request information about a particular AS:
whois -h whois.radb.net AS8
The aut-num object is shown below:

Aut-num objects provide a description of an Autonomous System's
routing policy. The "import" field in the example above tells you what
routes are imported by AS8; the "export" field tells you what routes
it exports.
