Requesting IPv4 blocks for End Users

Form


Políticas

Organization considered "end user" are those that will use the requested IP block for their own infra structure and not for providing services with those address to any other external organization.

To request an IPv4 address block the "end user" organization should fill up the template indicated above and then sent it to hostmaster@lacnic.net . Once it is verified and no error was found, an e-mail is sent back with the "ticket" number that identifies this request in our system.

After being approved, it will be necessary to pay the registration fee and sign the Registration Service Agreement. The instruction for payment and about the agreement is sent with the approval message. The assignment is only done after the payment and the reception of the agreement already signed.

Multihomed end user

If the applicant is a multi-homed end user or can prove interconnection needs with other autonomous systems:

The size of the minimum IPv4 address allocation to a multihomed end user is a /24, while the maximum is a /21.

In order to qualify for a block, the applicant must also satisfy the following requirements:

  1. If the user is not yet multi-homed but is planning to become multi-homed within a sixmonth window, or if the user is planning to establish interconnections with other autonomous systems during this window, a detailed justification must be presented.
  2. Justify the requested block size according to the utilization rate (section 2.3.3.4.2).
  3. Agree to renumber all blocks assigned by other ISPs within three months and return them to their original ISPs.

Requests for blocks larger than a /21 must also comply with the additional requirements established for non-multihomed end-users as described below.

Non-multihomed end user

If the applicant is a non-multihomed end user:

The minimum size of IPv4 assignments to a non-multihomed end-user is a /20 block. If their addressing needs are lower than a /20, end users will need to contact their ISPs in order to obtain addresses.

In order to assign a /20 to an end user, the following requirements must also be met:

  1. Have received a minimum assignment of 8 /24 prefixes from its Internet Service Provider.
  2. Agree to renumber out of the previously assigned space within a period of 12 months and return it to its original provider. This requirement is mandatory for obtaining the requested /20 prefix. The assigned /20 prefix must be used to renumber out of the addressing previously assigned by its provider.

If the applicant does not already have an IPv6 block assigned by LACNIC, simultaneously request an IPv6 block in accordance with the corresponding applicable policy.

Utilization Rate

Utilization rate is a key factor that must be justified in order to dimension the size of the assignment. Utilization rate is the percentage of IPv4 addresses that the organization will use within a specified period of time. The rate established according to RFC 2050 and adopted by LACNIC is:

  • 25% immediate utilization rate of the requested block.
  • 50% utilization rate of the requested block within one year.

A higher utilization rate may be required based on individual requirements. Should the organization presenting the application fail to comply with these parameters, addresses may be withdrawn and a reasonable period negotiated for their renumbering.

Additional assignments shall follow the policies set forth in Section 2.3.4 applicable to end users.

The organization requesting address block should be aware of the maintenance fee associated with the assigned block.
