ARIN IRR RESTful API User Guide

ARIN provides a way to automate creation and maintenance of Internet Routing Registry (IRR) records using an application programming interface (API) to ARIN’s database. (For an overview of ARIN’s IRR and additional information on how to submit objects and perform queries, visit the Internet Routing Registry page.)

You can use Representational State Transfer (REST) commands to add, update, or delete routing objects. These commands (also known as REST calls) are entered in a script or configured on the back end of a custom software program and are then submitted to the ARIN database to create, view, update, or delete records.

RESTful commands are structured to include the following:

  • the command method (such as GET, POST, and PUT)
  • a URL, or address of the RESTful server
  • other information, including your API key
  • (Optional) payloads

The command structure and payload formats are described in more detail in the following sections.

IRR REST Commands: Format and Example

IRR REST commands (also referred to as “calls”) generally have the format of method /URL/<object>/<objectID>/<objectName>?apikey=<api-key> where:

  • method is one of the following:
    • GET retrieves information about a record
    • POST creates a new record
    • PUT modifies an existing record
    • DELETE deletes a record
  • URL is the address of ARIN’s IRR RESTful server, https://reg.arin.net/rest/irr
  • object is the type of IRR object:
    • route
    • route6
    • aut-num
    • as-set
    • route-set
  • <objectID> is the identifying information for the object. This can contain multiple parts divided by the / character (for example, the IP address block, in CIDR format, of a route would have a / character in between the IP address and prefix length, or block size).
  • <objectName> is the name you have given the object
  • <api-key> is your API key that was configured using the Settings > Security Info > Manage API Keys option in ARIN Online. Visit API Keys for more information.

Note: The commands to create as-set and route-set objects are slightly different in that they append &orgHandle=ORGHANDLE to the end of the command; this is explained in the description of these commands.

To give an example of a typical command, the following command creates a route6 object:

POST https://reg.arin.net/rest/irr/route/2001:db8::/32/AS65536?apikey=APIKEY

REST commands also require headers and sometimes, when you’re creating an object, require a payload or a message body that contains the information of the object you’re creating in RPSL or XML format. Commands that require a payload are noted in this document.

Headers

IRR REST commands require these headers be used in your scripts or REST client software.

For all calls, the header must indicate either:

  • Accept: application/rpsl or
  • Accept: application/xml

If the call requires a payload, the header must include the Content-Type line (as shown in the following examples).

RPSL Header Example

Accept: application/rpsl
Content-Type: application/rpsl

XML Header Example

Accept: application/xml
Content-Type: application/xml

Payloads

Some REST calls require you to format and send information to ARIN with your command in a formatted “payload” file, or message body. IRR REST commands accept payloads in the following formats:

  • Routing Policy Specification Language (RPSL): Visit RFC 2622 for specifics of this format. RPSL is accepted only for IRR REST commands.
  • Extensible Markup Language (XML): This language consists of tags that identify data in the payloads, and is the language accepted for all of ARIN’s REST commands (including the suite of REST commands known as Reg-RWS that are used for tasks such as updating registration information for IP addresses and ASNs or reporting transferred resources).

Allowable Characters in Payloads

RPSL payloads allow the following encoding:

  • ASCII
  • UTF-8 in the descr: fields (also supported by the Internet Routing Registry Daemon [IRRd] database server software)

XML payloads support ASCII encoding only; however, comment fields which support free-form text (e.g., aut-num payloads) allow some UTF-8 encoding (characters for accented letters only).

If you are converting from email templates previously used with ARIN’s IRR system, you may want to format payloads in RPSL format (which is what email templates used). If you are developing new scripts to connect to ARIN’s API, you may want to use XML format for payloads.

Payload Examples

Examples of the payload required for the route-set object:

    <mpMember name="2001:db8::/32"/>
    </mpMembers>
</routeSet>

Note the following when constructing payloads:

RPSL payloads:

  • The mnt-by field is the prefix MNT and the Org ID of the organization that configures (maintains) the IRR object and manages the resource that is specified in the route object. It is in the format MNT-OrgID; for example, MNT-EXAMPLECORP. The mnt-by field for new IRR records created using IRR-online or IRR REST commands no longer has any relationship to legacy maintainer objects that were migrated from ARIN’s previous IRR system in June 2020.

All payloads:

  • The source field value must be ARIN. No other values are valid in this field.

Automation and Batch Processing

Multiple REST calls can be grouped together to automate creating, updating, and deleting IRR objects with a single script, or scripts can be set up to automatically send individual REST calls to ARIN. For example, you might configure scripts on the back end of your custom network software that send REST commands to ARIN whenever route objects are created, when the name of a route is changed, or when a route is deleted. Currently, only one action is supported in a single REST call. Batch processing, or performing multiple actions with a single REST call, is not yet implemented.

Objects

The following sections list the types of objects and how to create, view, edit, and delete the object.

Object Permissions

Viewing, editing, and deleting of some objects is limited depending on the method used to originally create the object; refer to this table.

route and route6 Objects

route objects are created for IPv4 routes and route6 objects are created for IPv6 routes. The only difference between these objects (aside from the type of IP address) is the payload content.

Payload in RPSL or XML format with the fields shown in the following tables.

RPSL Payload Fields
Field Definition
aut-num: The ASN for the routing policy.
as-name: An alphanumeric identifier for the aut-num object.
descr: In the description, enter any information you think needs to be here. This could be your name and address, your ISP’s name, or a network name or location.
admin-c: Admin POC for the organization that is maintaining the object. This field is the exact POC Handle as shown in Whois for the Org ID.
tech-c: Tech POC for the organization that is maintaining the object. This field is the exact POC Handle as shown in Whois for the Org ID.
mnt-by: The prefix MNT and the Org ID of the organization that configures (maintains) the IRR object and manages the resource that is specified in the route object. It is in the format MNT-OrgID; for example, MNT-EXAMPLECORP.
source: ARIN Do not use any other value; all objects must have this line.
member-of: The as-set (one or more) to which the object belongs. The as-set objects that are listed also need to include the maintainer associated with this aut-num in their object record for the cross reference to work.
import: Indicates the ASNs of the peers from which your AS will receive routing information and describes the routing information you’ll accept. 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: 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.)
default: Specifies the default routing policy (for example, if the AS should default to another AS for routing and under which conditions, such as if a specific filter is matched). More information is available in Section 6.5 of RFC 2622. (The mp-default field extends this function for IPv6.)

XML Payload Fields
Field Definition
autnum Use xmlns="http://www.arin.net/regrws/core/v1".
creationDate Ignored by system.
description In the description, enter any information you think needs to be here. This could be your name and address, your ISP’s name, or a network name or location. Use line numbers for each line of information, as shown in the payload example.
lastModifiedDate Ignored by system.
orgHandle The Org ID of the organization that configures (maintains) the IRR object and manages the resource that is specified in the route object.
pocLinks Admin (AD), Tech (T), or Routing (R) POC for the organization that is maintaining the object. This field is the exact POC Handle as shown in Whois for the Org ID. Use the pocLinkRef tag for each individual POC, as shown in the payload example.
source Must be ARIN.
netHandle Name of the network.
asName An alphanumeric identifier for the aut-num object.
asNumber The ASN for the routing policy.
default Specifies the default routing policy (for example, if the AS should default to another AS for routing and under which conditions, such as if a specific filter is matched). More information is available in Section 6.5 of RFC 2622. (The mpDefault field extends this function for IPv6.)
memberOf The as-set (one or more) to which the object belongs. The as-set objects that are listed also need to include the maintainer associated with this aut-num in their object record for the cross reference to work.
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 mpExport field extends this function for IPv6.)
import Indicates the ASNs of the peers from which your AS will receive routing information and describes the routing information you’ll accept. 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.)
mpDefault Specifies the default routing policy as in the “default” field, but extends RPSL to allow “multi-protocol” routing policy. More information is available in Section 2.5 of RFC 4012.
mpExport Describes export policies as in the “export” field, but extends RPSL to allow “multi-protocol” routing policy. More information is available in Section 2.5 of RFC 4012.

Error Codes

This list includes some of the error codes that may be returned if you send an incorrect command or payload. A message is returned with additional information on the error; the following table provides some additional information on errors that may be returned. (Tip: Use your browser’s search feature to find a specific message.)

400 Bad Request

Some of the causes of a 400 Bad Request response are provided in the following sections:

  • E_AUTHENTICATION: The API key specified was missing or invalid.
  • E_BAD_REQUEST: An aut-num object with the specified ASN already exists.
  • E_ENTITY_VALIDATION:
    • The payload entity failed to validate; refer to the component messages for details.
    • Changing the value of the mnt-by field is not supported. The mnt-by value in the call does not match the mnt-by value of the existing record or the Org Handle (Org ID) of the organization that maintains the resource.
    • Prefix: Unable to create a route with this prefix. Make sure that your organization, as specified in the mnt-by field (MNT-OrgID) in your payload, manages the IP address block specified in your request.
    • Each specified tech-c must match a Tech or Routing Point of Contact (POC) associated with the Org ID (as shown in Whois) that is specified as a maintainer in the mnt-by field. One or more tech-c fields are not valid Tech POCs for the specified organization.
    • A route object with the specified prefix and origin already exists.
    • Changing the origin of a route object is not supported. You cannot modify a route or route6 object to change the ASN origination; you need to delete the object and submit a new route or route6 object with the desired new ASN.
    • Duplicate entries are not allowed. Duplicate members in the member-of attribute are not supported.
