About this network

An airline holding a hundred and thirty-one thousand addresses, most of them registered to nobody at all.

What it's used for

• An airline's own network. Seventy-five IPv4 prefixes announced from the United Kingdom, no IPv6, one hundred and thirty-one thousand and seventy-two addresses, across three observed BGP neighbours.

Notable

• The blocks split into two families. One carries a five-character netname and a registrant that is literally unknown; the other carries the same name with a digit two and is registered to a cable operator's address management team, with the airline second.
• Those five characters are the airline's initials plus a third letter, which is how it is identified in operational systems rather than in company records.
• The AS handle is the company name in plain words with no suffix, no country code and no letters for an autonomous system.
• Seventy-five separate announcements for what is a contiguous pair of ranges.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Registrant unknown on a routed block usually means the space predates the modern registry: it was assigned directly, before anyone was required to record who held it, and the record has never been rebuilt because nothing forces it.
• An airline needs an enterprise network at every airport it flies to, which is what a hundred and thirty-one thousand addresses and seventy-five routes look like from outside.
