Legacy resources are resources that were assigned before the creation of Regional Internet Registries (RIRs). Any Internet resource (IP address block or ASN) assigned prior to 28 December 1997 is regarded as a legacy resource. Once established, the RIRs took over the task of assigning Internet resources.
Since their creation each RIR began to develop and use its own Internet resource assignment policies. This is an important distinction.
Resources assigned after 28 December 1997 have followed existing policies proposed and approved by the regional community. These resources are subject to assignment fees, as well as to renewal and maintenance fees.
In the case of LACNIC, organizations receiving IPv4 address blocks (whether as ISPs or End Users) become part of our membership base and thereby obtain the rights to: attend the events and training activities organized by LACNIC; vote in the various elections held by the organization; and participate in member assemblies with full voting and speaking privileges.
Organizations that have received legacy resources can also become LACNIC members. They must go through the process of completing a membership application form and paying the corresponding membership fee. Further details are available here.
An organization may transfer legacy resources provided that the transfer is the result of a legal operation, which can be verified with appropriate documentation. Further details are available here.
Transferred legacy resources will no longer be considered as such. If the transferred resources are IP address blocks, the organization receiving custody of such resources will have membership rights. Transferred resources will be subject to renewal fees.
Organizations holding legacy IP blocks may not request additional IPv4 addresses because the region has entered IPv4 Exhaustion Phase 3. However, they may request IPv6 addresses or ASNs.
Once the assignment of an additional block is approved (only IPv6, or IPv4 in the case of a transfer) the previous blocks will no longer be regarded as legacy resources. In this case, the organization must become a LACNIC member and will be subject to the applicable renewal fees. The organization's category will be calculated considering both the newly approved additional address block, as well as any prior blocks the organization may have held.
