AS13579 — INFOTEC CENTRO DE INVESTIGACION E INNOVACION EN TECNOLOGIAS DE LA INFORMACION Y COMUNICACION

AS13579 announces 18 IPv4 prefixes covering 22,016 addresses and 0 IPv6 prefixes.

About this network

Every address is labelled by role in reverse DNS, and one of the broadcast labels names the wrong subnet.

What it's used for

• A public research centre for information and communication technology. 22,016 addresses across thirty-four IPv4 prefixes, two observed BGP neighbours, and no IPv6 announced.

Notable

• All eighteen sampled addresses answered, each prefixed subnet-, brdcst- or host- before the address.
• 200.38.161.255 answers as brdcst-200.38.160.255, naming a different subnet than the one it is in.
• Netnames are the address range written out with a hyphen between the first and last address.
• Two prefixes failed their registry lookup, so nothing is known about their registration here.
• First seen in the routing archive on 2005-05-07, an actual date rather than the archive's start.

Interesting

• Labelling each address by its role in the subnet is generated documentation. It says where every boundary falls, so anyone reading the zone learns the subnet layout without probing for it.
• The mismatched broadcast label is the generator's arithmetic going wrong once, and it is only visible because the scheme is otherwise perfectly regular. A zone with arbitrary names would hide it.
• Netnames that are the range itself are the registry's own convention in this region, which makes the field a duplicate of the block and useless for saying who or what is inside it.
