AS15720 announces 5 IPv4 prefixes covering 5,120 addresses and 0 IPv6 prefixes.

About this network

The AS handle is a street address and a house number, with no company name in it at all.

What it's used for

• The national postal and financial group's network. Five IPv4 prefixes announced from Italy, no IPv6, five thousand one hundred and twenty addresses, across two observed BGP neighbours.

Notable

• The handle is an avenue name, a comma and a building number. Nothing in it identifies the holder, the brand or the network.
• All five blocks are pieces of one range, announced from a /21 down to a /23, with the covering block never announced on its own.
• Their netnames share a country code and a subsidiary's brand, with three different allocation dates, two of them more than a decade apart.
• Three of the five blocks list only the subsidiary's staff object. The parent company appears on the other two.
• Fifteen addresses were queried for reverse DNS and none returned a name.
• There is no IPv6 announcement.

Interesting

• This is the street address in an AS handle taken to its conclusion. Others in this range append an address to a company name; here the address replaced it, and the routing identifier for a national institution is a building.
• Splitting one allocation into five announcements and never carrying the cover costs every network on the internet four extra routes. It usually means the pieces were turned up separately and nobody went back.
