About this network

The contact on every block is a department's initials followed by the name of its web team.

What it's used for

• A municipal government's network. Eleven IPv4 prefixes announced from the United States, no IPv6, twelve thousand two hundred and eighty-eight addresses, through two observed BGP neighbours.

Notable

• All eleven blocks come from one parent range, carry the same netname, and list the same contacts. The netname is three letters for the city and three for a government.
• Beside the city, each block names a contact built from three initials for a technology department and then a mixed-case word joining the city's abbreviation to the word for the web.
• The pieces come at three sizes and are scattered through the parent range rather than adjacent, so none of them can be combined.
• The AS handle spells the city out in three hyphenated words, including the joining word that the netname drops.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• A web team as the registered contact for the whole city network is a snapshot of which office owned the internet when the paperwork was filed. The addresses outlived the org chart, and the record still points at the team that was in charge of the front page.
• Publishing nothing in reverse DNS is a choice, and for a city it is the quieter one. Every address here belongs to a government, and none of them says so to anyone who asks the resolver.
