Even though the IANA (Internet Assigned Numbers Authority) announced the exhaustion of the central pool of 16-bit ASNs (Autonomous System Numbers) in August, LACNIC still has 16-bit ASNs in stock for its Latin American and Caribbean members, reported Sergio Rojas, Head of LACNIC’s Registration Services Department.<\/p>\n
The policies adopted by the community for managing its number resources have allowed LACNIC to continue to have both types of existing ASNs: 16-bit and 32-bit.<\/p>\n
An ASN is a number used to group IP networks having their own independent routing policy: they manage their own traffic with other autonomous systems on the Internet. \u201cIf we think about IP addresses as a house’s street name and number, the ASN is the post code for the area,\u201d explained Rojas.<\/p>\n
Until 2007, autonomous system numbers were defined by a 16-bit integer, but this allowed assigning a limited amount of ASNs. As demand increased, more autonomous system numbers were needed. This led to the creation of 32-bit autonomous systems.<\/p>\n
Since 2011, LACNIC assigns 32-bit ASNs to its members by default. However, in case of incompatibility with a member’s equipment, LACNIC may authorize a swap of this 32-bit ASN for a 16-bit ASN.<\/p>\n
\u201cThere is no advantage or disadvantage in using one (16-bit ASN) or the other (32-bit ASN). It’s simply a matter of equipment compatibility. Certain older devices do not support 32-bit ASNs,\u201d added Rojas.<\/p>\n
Current equipment trends mark that the use of 32-bit ASNs will be the norm. \u201cAssignment behavior in the LACNIC region shows that this protocol is being used without problems, as 32-bit ASNs are assigned by default,\u201d noted the Head of LACNIC’s Registration Services Department. In the past twelve months, LACNIC has assigned 842 32-bit ASNs and 42 16-bit ASNs.<\/p>\n","protected":false},"excerpt":{"rendered":"
