Requesting IPv4 blocks for End Users
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.

If the applicant is a multihomed end user or it has needs of interconnection:

The size of the minimum IPv4 address assignment to a multihomed end user is a /24. In order to qualify for a block the applicant must also satisfy the following requirements:
  • Have received an assignment equivalent to a /25 from its Internet Service Providers.
  • Agree to renumber out of all the blocks allocated by providers within a period of 3 months and return the space to its original 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.
The maximum prefix size that may be assigned shall be a /24 and the minimum a /21. Initial assignments of a block larger than a /21 must follow the additional requirements established for non-multihomed end users described below.

Those users that are planning to be multihomed or that are planning to establish interconnections with other autonomous systems in a period of six months can also apply. In these cases, they will have to justify with detail.

If the applicant is a non-multihomed end user:

The size of the minimum IPv4 address assignment to a non-multihomed end user is a /20 block. Should the need for IPv4 address space be smaller than a /20, in order to obtain the required addresses end users should contact their corresponding Internet Service Providers.

In order to assign a /20 to an end user, in addition to the previous requirements, the following shall be satisfied:
  • Have received a minimum assignment of 8 /24 prefixes from its Internet Service Provider.
  • 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 essential 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.
The utilization rate is used to determine the prefix size to be assigned. Rates to be considered:
  • 25% of immediate utilization of the requested block and
  • 50% of utilization in one year.
In both cases the organization should agree to return the previous assigned block to their upstream provider.

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