To request an allocation, your organization must first establish Point of Contact (POC) handles and an Organization Identifier (Org ID). Only the Admin and Tech POCs with an ARIN Online link to the Organization are allowed to submit resource requests.
Note: If this is your first time requesting resources, please visit the Getting Started page.
How to request resources
The following links provide information on the requirements for receiving specific types of resources and details about the request processes available.

IPv6 addresses are organized into a topological hierarchy, consisting of a public topology, a site topology, and interface identifiers. The public and site topologies comprise the network portion of the address, while the interface identifiers form the host portion. RFC 3513 describes this addressing hierarchy in more detail.
The exact policies covering the delegation of IPv6 resources can be found in the Number Resource Policy Manual (NRPM).
Allocations of IPv4 address space are made to organizations like Internet Service Providers (ISPs) for the purpose of reassigning space to their customers. Assignments of IPv4 address space are made to end-user organizations for running internal networks, and not for sub-delegation of those addresses outside their organization. End-users who are not connected to an ISP and/or who do not plan to connect to the Internet are encouraged to use private IP numbers reserved for non-connected networks.
If you are unsure whether you are an ISP or an End-user, send an message to ASK ARIN via ARIN Online, or email firstname.lastname@example.org and provide detailed information as to how you use address space to support the products/services you offer.
The exact policies covering the delegation of IPv4 resources can be found in the Number Resource Policy Manual (NRPM).
Note: ARIN activated the Wait List for Unmet IPv4 Requests on 01 July 2015. We are still processing and approving customer IPv4 requests. Visit our Waiting List page to learn more about your options and the wait list process.
Autonomous System Number (ASN)
An Autonomous System is a connected group of IP networks that adhere to a single unique routing policy that differs from the routing policies of your network's border peers. An ASN is a globally unique number used to identify an Autonomous System. An ASN enables an AS to exchange exterior routing information with neighboring ASes. Sites that do not require a unique ASN should use one or more of the ASNs reserved for private use. Those numbers are 64512 through 65535.
The policies governing AS number allocation and maintenance can be found in the Number Resource Policy Manual.
Experimental Internet Resource Allocations
Experimental Allocations are granted on a lease/license basis for a period of one year. At the end of the experiment, all allocated resources will be returned to the available pool. ARIN will only make one-off allocations annually to any applicant. Additional experimental allocations must be separately justified under separate application.
The policies governing Experimental Internet Resource Allocations can be found in the Number Resource Policy Manual.
The Appeals Process allows organizations to appeal an ARIN decision regarding a number resource request if the organization believes that the community-established policies and procedures for the administration and management of Internet number resources were not adhered to.
Reissuing Returned, Revoked, and Reclaimed Resources
There are a number of ways that previously issued number resources can come back to ARIN. IP addresses or AS numbers may be revoked for nonpayment of fees, they may be voluntarily returned by the holder, or they may be reclaimed by ARIN in instances of confirmed fraudulent activity or abandonment of resources.
All returned, revoked, and reclaimed IPv4 addresses are held for a period of 60 days prior to being reissued to allow adequate time for the resource to clear any route filters, and to allow an organization the opportunity to pay their overdue fees. This hold period was reduced as part of ARIN's transition into Phase 4 of the IPv4 Countdown Plan.
ARIN will continue to hold IPv6 addresses and AS numbers for six months prior to reissue.
