In compliance with section 3.2 of LACNIC's Policy Manual, on January
1st 2009 the second phase of the ASN policy was implemented.
As already mentioned in our previous communication on October 1st
2008, beginning on January 1st 2009, every ASN request received by
LACNIC will be assigned by default 32 bits ASNs; 16 bits ASNs will
only be assigned if explicitly requested.
The express request for 16bits ASNs should be done either by filling
the 6a field ("Additional Information") in the ASN request template
or by email during the request process.
