About this network

The reverse names give a building letter and a room number before they give the address.

What it's used for

• A university and its city network. Nine IPv4 prefixes and one IPv6 /32 announced from Poland, thirteen thousand and fifty-six addresses, across four observed BGP neighbours.

Notable

• Two answering names are the university's initials, a letter, a three-digit number and the last octet, so a lookup identifies a building and a room before it identifies the machine.
• A third is a short name for an outward-facing router, which is the only host in the sample not described by where it physically sits.
• Six netnames are a country code, the network's name and a date, with one date written in six digits and the others in eight.
• Two more are the university's initials and a digit, and those digits are four and seven, with the numbers between them absent from the record.
• One block's netname is just the network's name, with nothing else.
• Of eighteen addresses queried, three returned a name.

Interesting

• Campus networks were built before addresses were scarce, so the naming grew out of the estates department rather than the routing plan. A letter and a room number is how the people who pull the cables think about a machine.
• A metropolitan academic network is a university acting as an internet provider for a whole city's institutions, which is why a single university holds thirteen thousand addresses across nine routes.
