About this network

A cultural and educational body holding legacy address space, with netnames that are just the ranges written out.

What it's used for

• A Mexican cultural and educational organisation's network. 768 addresses across three IPv4 prefixes, the IPv6 block 2801:f0:20::/48, and three observed BGP neighbours.

Notable

• All three blocks are registered to the organisation itself.
• Each netname is that block's first and last address with a dash between them, rather than a name.
• Two of the blocks sit in 192.100, space handed out long before the current allocation system.
• Nine addresses were queried for reverse DNS and none returned a name.

Interesting

• The regional registry that serves this part of the world fills the netname with the range itself, so the field that elsewhere carries brands, typos and dead company names carries no information at all here. It is a different answer to the same problem, and it never goes stale.
• An educational body with legacy space, its own AS number and three upstreams is a survivor of the period when universities and cultural institutes were among the few organisations connected at all. The blocks are small because nobody expected them to need more.
• Silence in reverse DNS across all three ranges is unusual for an institution, which usually names its mail and web hosts if nothing else.
