Proposal Data

Policy Type: LACNIC
Id: LAC-2019-6
Last version: 1
Presented at: LACNIC 31 Presentations:


This purpose of this proposal is to specify that resources are assigned in an exclusive capacity, as noted in various sections of the Policy Manual.

2.2.2. - The Internet Registry System
“The Internet registry system has been established with the aim of enforcing the objectives of exclusivity, preservation, routability and information.” - Validity of IPv4 Address Allocations
“IPv4 address allocations are valid as long as the objectives of exclusivity, preservation, routability and information continue to be met.”


It is important to clearly specify this, so that any potential user of the Policy Manual will know that it applies equally to all resources, that only the original recipients of assigned or allocated resources have rights over such resources, and that only the original recipients may determine whether –and when– a specific resource is used in their own network or in others. This even responds to technical reasons (typically IETF standards), as Internet resources may generally not be used simultaneously in different networks, except in the case of “anycast” uses (e.g. CDNs) which are under the administrative control of the original recipient of the resources.

Likewise, the information on record regarding where the resources are being used should be reliable, as this is one of the most important principles of an RIR.


1.0 Resources Are Assigned in a Unique and Exclusive Capacity

LACNIC assigns Internet resources in a unique and exclusive capacity. Standards do not allow simultaneous or duplicate uses of the same resource on different networks that are under different administrative control, except for explicit cases such as anycast.

Therefore, only the original recipient may decide that such resources will be used in other networks and/or under the administrative control of a different entity, in strict observance of the policies in force and maintaining the consistency of the registry information.

Additional Information

The author believes that this proposal should become a new section of the Policy Manual, possibly located before the appendixes. However, given their editorial nature, the exact position and numbering will be left up to the LACNIC staff.




Other RIRs are working on similar proposals. If necessary, equivalent proposals will be presented in each one.
