ARIN IRR User Guide
Overview
ARIN’s IRR is a searchable database of routing policy information for networks in the ARIN region. Objects in the IRR contain routing information in the specific format of Routing Policy Specification Language (RPSL). ARIN Online provides a method to create IRR objects by entering information into a window in the graphical user interface (GUI), and the corresponding RPSL objects are created by the system. This method of managing IRR objects is referred to as IRR-online.
ARIN’s earlier IRR system, where objects are managed via email templates, is described in the ARIN IRR-email System page and is only available to organizations who had maintainer objects in that system before June 2020 and who have not transitioned to IRR-online.)
Navigating IRR-online
To access IRR-online, log in to ARIN Online and choose IRR Object Records from the navigation menu. You can choose the type of objects you want to add, edit,* or delete:
route(6)
: (Used to signify aroute
or aroute6
object.) Aroute
(IPv4) orroute6
(IPv6) object specifies the Autonomous System Numbers (ASNs) that originate specific IP address prefixes. Note:route
androute6
objects are configured using the same window in ARIN Online, butroute
objects are routes that originate IPv4 prefixes androute6
objects are routes that originate IPv6 prefixes.as-set
: This object defines a group of ASNs that are peers in the routing network and through which traffic can be routed. Theas-set
members can include ASNs as well as the names of otheras-sets
.aut-num
: This object specifies an ASN and its routing policies.route-set
: This object is a record that defines a group of IP address prefixes or otherroute-sets
. Route sets are used inaut-num
objects and otherroute-set
objects. (Aroute-set
is not a group of IRR databaseroute
objects.)
* Note that IRR objects migrated from the IRR-email system cannot be edited in ARIN Online.
IRR Permissions
Admin, Tech, and Routing POCs can manage IRR records. Resource POCs cannot manage IRR records.
Caution for IRR-email Users
If your organization previously used ARIN’s email template-based IRR system, and you are creating an object in IRR-online on behalf of that organization, the system will warn you that adding or deleting objects in IRR-online will prevent that organization from continuing to use IRR-email. If you need continued access to IRR-email for that organization, do not add or delete objects in IRR-online.
Searching for IRR Routes
In the IRR route(6) Objects page, choose If you would prefer to search for specific IRR routes, click here. Enter the prefix (for example, 2001:db8::/32
) for the IP address range or an IP address in the range (for example, 2001:db8:e1fc:5f2d:c886:25cf:3995:7d18
) and choose Search Routes. Wildcards are not accepted. You’ll receive a list of route(6)
objects with “source: ARIN” that contain that prefix or address. Nonauthenticated objects will not be listed, but are available in the ARIN-NONAUTH stream/source in NRTM and FTP, and in Whois Port 43.
Viewing route(6) Objects
A route(6)
object specifies the IPv4 or IPv6 address prefix and the ASN of the autonomous system from which the route originates. Choose route(6) from the navigation bar to view a list of route
and route6
objects that are associated with your user account. They are displayed by Org ID and organized within Org ID by prefix.
Note: route(6)
is used to signify a route
or a route6
object.route
and route6
objects are configured using the same window in ARIN Online, but route
objects are routes that originate IPv4 prefixes and route6
objects are routes that originate IPv6 prefixes.
Select a prefix to view an individual route(6)
object. The object fields are described in the following table (some fields listed are optional, and some only apply to objects migrated from the IRR-email system).
Field Name | RPSL Field Name | Definition |
---|---|---|
Prefix | route or route6 | The CIDR prefix of the route to be originated. Together with the origin: attribute, constitutes the primary key of the route object. |
Origin | origin | The ASN from which the route originates. |
Maintained By | mnt-by | The Org ID of the organization that configures (maintains) the IRR object and manages the IP address prefix that is specified in the route object. The system applies the RPSL prefix MNT- automatically. |
Description | descr | Text entered to describe the route. This could be, for example, the organization name and mailing address, or physical location of the routing equipment. |

Administrative Contact | admin-c | The Admin POC for the organization that is maintaining the object. |
Member Of | member-of | This field lists any route-set objects which can include this Prefix. Those route-sets must also reference this object by listing the Org ID of the maintainer of this route(6) object in the “Members by Reference” field. See the example following this table. |

Last Modified | last-modified | Date and time the record was last modified in IRR-online. |
Creating a route(6)
Object
Note: route(6)

or a route6
object. route
and route6
objects are configured using the same window in ARIN Online, but route
objects are routes that originate IPv4 prefixes and route6
objects are routes that originate IPv6 prefixes.

For example, you can configure your routing to import a set of routes from a specific ASN that matches a filter, such as an IPv4 address. You can also specify actions to set or modify route attributes (such as assigning a preference to a route). More information is available in Section 6.1 of RFC 2622. (The “mp-import” field extends this function for IPv6.) |
Export | export | Describes export policies (for example, exporting or announcing a set of routes or routes that match a filter) to specified ASes. More information is available in Section 6.2 of RFC 2622. (The “mp-export” field extends this function for IPv6.) |

More information is available in Section 6.5 of RFC 2622. (The “mp-default” field extends this function for IPv6.) |
MP Import | mp-import | Describes import policies as in the “import” field, but extends RPSL to allow “multi-protocol” routing policy. More information is available in Section 2.5 of RFC 4012. |
