About this network

One /20 serving Italy's cooperative banks, under three names that share no letters.

What it's used for

• IT and network services for a cooperative banking group. 4,096 addresses in a single /20, one observed BGP neighbour, and no IPv6 announced.

Notable

• The AS handle is ISIDE-AS, the netname is IT-FEDLO-20000824, and the registrant is BCC Sistemi Informatici S.P.A. — three different names on one block.
• The registry contact is a role, BCC SI Contact Role, rather than a person.
• The whole inventory is 217.12.128.0/20, dated August 2000 in the netname.

Interesting

• Three names is one more than usual and each belongs to a different layer. BCC is the cooperative credit banks themselves, FEDLO reads as the regional federation that groups them, and ISIDE is the shared IT company they own between them. The stack is visible because each field was filled in by a different part of it.
• Italian cooperative banking is organised as hundreds of small independent banks with shared services in the middle, so a single /20 and a single upstream serves an institution that has branches in most towns in the country. The network is centralised even though the banks are not.
• A contact recorded as a role rather than a named person is the practice that abuse handling eventually made mandatory everywhere. This record had it in 2000, which is early.
