Policy Type: LACNIC
Id: LAC-2013-2
Last version: 1
Presented at: LACNIC 20 Presentations:


To group the principles governing the distribution of Internet number resources in a single, initial paragraph. Some of these principles are detailed in the text on IPv4 distribution, while others are described in the section on IPv6. These principles, however, generally apply to all numbering resources and should consequently be included at the beginning of the document.
Also, remove all references to RFC2050 as it is now classified as historic.
The principles set forth in RFC2050 should be detailed in the first chapter of the policy document.


RFC2050 is now classified as historic, so it is now important include the principles governing number resource distribution in the policy manual.
Some of these principles were initially included in the chapter dealing with IPv4 distribution. Most were later duplicated in the IPv6 chapter. These principles govern the distribution of numbering resources, which also include ASN numbers. Consequently, they should be included in an initial chapter and not be specifically associated with one type of resource or other.


"IP address allocation follows the hierarchical scheme described in RFC 2050"
"IP address allocation follows a hierarchical scheme"

Under “Definitions”
"IP address allocation follows the hierarchical scheme described in RFC 2050. Responsibility for the administration of IP address space is distributed globally in accordance with the hierarchical structure shown below."

"IP address allocation follows a hierarchical scheme. Responsibility for the administration of number resources is distributed globally in accordance with the hierarchical structure shown below."

Add new chapter:
"1.11 Principles for Proper Administration and Stewardship
The fundamental principle is to distribute unique Internet numbering resources according to the technical and operational needs of the networks currently using, or that will use, these numbering resources, allowing the sustainable growth of the Internet.
The numbering resources under the stewardship of LACNIC must be distributed among organizations legally constituted within its service region [COBERTURA] and mainly serving networks and services operating in this region. External clients connected directly to main infrastructure located in the region are allowed.
"Anycast" services that use numbering resources outside said region are acceptable as long as they are provided by an organization legally constituted within the service region [COBERTURA] and at least one copy of the service is hosted on local infrastructure.

1.11.1 Rational Distribution
Internet numbering resources must be distributed ensuring their uniqueness and considering the technical and operational needs of the networks and infrastructure that use them.
Considerations must be made to take into account potential limitations on the availability of each numbering resource at the time of their distribution.

1.11.2 Public Information Registry
Providing a public registry of information relating to the numbering resources that have been distributed is a fundamental requirement for the Internet numbering resources distribution system.
Aimed mainly at ensuring the resources' uniqueness while providing usage and contact information in case operational or security problems arise.
Also, to allow analyzing the use of these resources.

1.11.3 Hierarchical Distribution
The hierarchical distribution of Internet numbering resources seeks to contribute to the Internet routing system's scalability, allowing resources to be grouped and announced as concisely as possible.

In some cases, the goals mentioned above may be in conflict with each other or with the particular interests of the requesting organizations. In these cases, a careful analysis of each particular situation is required so that an appropriate compromise can be reached among the conflicting parties.

IPv4 Policy.

Remove Chapter 2.2.2

In 2.3.1
"As previously mentioned, LACNIC's allocations to IRs are based on the slow-start procedure described in RFC 2050"
"... based on RFC 2050"
"According to the provisions of RFC 2050..."
"When assigning IPv4 addresses to end users, LACNIC follows the guidelines of the assignment policies and procedures established in RFC 2050. These guidelines and policies were developed to satisfy the needs of the growing Internet community in relation to preserving the limited IPv4 address space and allowing the continuity and existence of Internet routing technologies."

" established according to RFC 2050"

IPv6 Policy

Remove Chapter 4.3

Move 4.3.9 on the inclusion of ASN information in the WHOIS database to a different chapter.
