About this network

Both of its netnames are written as ranges with a dash, and one of them describes a block sixteen times larger than what is announced.

What it's used for

• A university's network. 6,144 addresses across two IPv4 prefixes, with three observed BGP neighbours and no IPv6 announced.

Notable

• 200.49.224.0/20 carries the netname 200.49.224.0 - 200.49.239.255, registered to the university itself.
• 170.210.184.0/21 carries 170.210.0.0 - 170.210.255.255, registered to Red de Interconexion Universitaria.
• Six addresses were queried for reverse DNS and none returned a name.

Interesting

• Writing a netname as a first and last address separated by a dash is a registry convention that predates the notation everyone now uses, where a block is a starting address and a length. The older form survives here in a record that has never needed rewriting.
• The second netname covers a far wider range than the university announces, because the block belongs to the national academic interconnection network and the university holds a slice of it. The registry names the pool; routing shows the portion.
• Three neighbours for a campus that announces both its own space and its slice of the academic network is the standard arrangement in a country where research traffic and commercial traffic take separate paths.
• Nothing answers a reverse lookup, which for a university is unusual enough to be a decision rather than neglect.
