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
-h parameter tells the whois client on your machine that you want to talk to the IRRd whois server):
whois -h whois.radb.net 184.108.40.206/16
The output includes an RADB "Route object" containing information about the network:
route: 220.127.116.11/16 descr: UONet University of Oregon Computing Center Eugene, OR 97403-1212 USA origin: AS3582 mnt-by: MAINT-AS3582 changed: [email protected] 19960222 source: RADB
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: AS8 as-name: RICE descr: Rice University AS import: from AS2914 action pref=100; accept RS-ALL import: from AS4557 action pref=100; accept RS-ALL import: from AS7276 action pref=100; accept RS-ALL import: from AS3356 action pref=100; accept RS-ALL export: to AS2914 announce ANY export: to AS3356 announce ANY export: to AS4557 announce AS8 export: to AS7276 announce ANY tech-c: CF2182 admin-c: FG50 notify: [email protected] mnt-by: MAINT-AS8 changed: [email protected] 20050205 source: RADB
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.
There are two different sets of query flags that can be used to query the RADB. whois.radb.net supports queries with both types of flags:
- ! RADB Query Flags
- - RIPE Query Flags
In any one query you cannot combine a RIPE flag with a RADB flag.
If you plan on making a large number of queries please invoke a persistent tcp/ip session. This is done by telneting directly to whois.radb.net and issuing the !! command. This will spare our server having to establish and teardown connections for every query.

We support the following IRRd commands.
!g Get routes with specified origin. Example: % whois -h whois.radb.net '\!gas237' !6 Get IPv6 routes with specified origin. e.g., !6as1234. This is the IPv6 equivalent of the '!g' command. !i Return members of an as-set or route-set. Optionally, recursively expand members of all sets within the named set. !iAS-ESNETEU # non-recursive, don't expand # any embedded as-set's !iAS-ESNETEU,1 # expand any embedded as-set's !iRS-FOOBAR,1 # recusive expansion of a route-set !j performs distributed checks on database synchronization. This command makes it possible to view the mirror status (oldest journal number, CURRENTSERIAL) for a database. If a : is present after the range, the database was last exported at that serial number. For example: !jRADB,RIPE,
, !j-* # Show all databases Output: A RADB:Y:1000-2000 VERIO:Y:3500-4500:4000 RIPE:N:0-666 FOO:X: BAR:X: C Y means that the database is mirrorable. N means that the database is not mirrorable, but the local IRRd server is reporting the current serial number. You can use this option to check for updates. The first number will _always_ be zero. The second number may be zero if the CURRENTSERIAL file doesn't exist. X means that the database doesn't exist, or the local server is denying information about an existing database for administrative reasons. Returned databases are canonicalized to upper case. !m Match an object of the specified type with the specified key. Return immediately after first match. Example, !maut-num,as701 #lookup aut-num object Example, !mmntner,maint-as237 #lookup mntner object !n Identify the tool for statistics/logging purposes. Example, !nRoe !o Display all objects maintained by a given mntner name. Example, !oMAINT-AS237 !q Quit the IRRd session. Example, !q !r Perform route searches. Default finds exact prefix/len match. o - return origin of exact match(es) l - one-level less specific L - all less specific M - all more specific Example, !r141.211.128/24,l !s Set the sources to the specified list. Default is all sources. Default search order is the order in which sources are configured in the irrd-conf file. Example, !sradb,ripe,savvis lc - show the currently selected sources Example, !s-lc !v Provide the IRRd version number. Example, !v
We support the following RIPE commands.
-s Set the sources to the specified list. Example -s radb -m First level more specifics of a route object Example: -m 188.8.131.52/20 -M All level more specifics of a route object Example: -M 184.108.40.206/20 -l First level less spefics of a route object Example -l 220.127.116.11/20 -L All levels less specfics of a route object Example -L 18.104.22.168/20 -i mnt-by Find objects associated(mnt-by) a specified maintainer Example -i mnt-by MAINT-AS237 -i origin Find objects with a specified origin AS Example: -i origin AS237 -t Show the template for specified object type Example: -t route -k Establish a persistent connection Like the !! command, this prevents the closure of the connection after the initial query -K Return only primary key for specified object Example: -K MAINT-AS237 -T Return only objects of specified type Example: -T route 22.214.171.124/20 -g for mirroring purposes
