Those interested in obtaining an IPv6 address allocation will find the corresponding policies and forms at:

http://www.lacnic.net/en/registro/ipv6.html

In general, a LIR (local internet registry) can obtain a /32 block as an initial allocation.

As part of the actions that LACNIC is implementing in order that the new protocol may be deployed in the region, IPv6 blocks have no cost for those who have already been assigned IPv4 blocks by the RIR.
