AS12835 TRENTINODIGITALE-AS

An Italian province's own IT company, with 33 neighbours and a netname stamped December 1999.

What it's used for

• The public ICT company of an autonomous Italian province, serving regional government and public bodies. 9,472 addresses across six IPv4 prefixes, 33 observed BGP neighbours, and no IPv6 announced.

Notable

• Four /21s carry the bulk: 46.226.200.0/21, 77.72.192.0/21, 109.205.104.0/21 and 194.105.48.0/21.
• Netnames run IT-INFOTN-19991202, 20070219, 20100212, 20110125 and 20131028.
• 193.43.34.0/24 is ITEA-WAN, registered to the province's public housing institute.
• Eighteen addresses were sampled and none returned a name.

Interesting

• INFOTN is not the company's name. It abbreviates what the organisation was called when the first block was issued in 1999, and every allocation since has been filed under the same prefix for continuity. Netnames become internal identifiers the moment the first one is chosen, and renaming them would break more than it fixed.
• A separate public body's wide-area network sits inside these announcements under its own netname. That is the shape of a regional IT authority: it does not just run its own network, it runs everyone else's, and the registry records each tenant separately.
• 33 neighbours for fewer than ten thousand addresses is a lot of interconnection. A provincial network peers with municipalities, health services, schools and the national research network, and each of those relationships shows up as a neighbour regardless of how much traffic crosses it.
