About this network

Ten routes in two identical groups of five, the second an exact copy of the first.

What it's used for

• A bank's network. Ten IPv4 prefixes announced from Italy, no IPv6, eight thousand addresses, through one observed BGP neighbour.

Notable

• All ten blocks come from one range, and they split into two groups of five with the same shape: a /21, two /24 prefixes, a /23 and a /22, in that order.
• Each group covers four thousand and ninety-six addresses, and the second group sits immediately above the first.
• One block's registry lookup failed, so its netname and registrant are unknown rather than absent.
• Eight of the netnames carry a third party's code and one allocation date; two carry a different short code matching the start of the AS handle.
• The corporate form in the holder's name is written in full capitals in one field and in mixed case in another.
• Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

• Two identical five-route patterns is a network deployed twice, almost certainly to two sites built from the same plan. The address layout is a floor plan.
• Ten routes where two would do costs the rest of the internet eight extra table entries, and the symmetry shows it was designed that way rather than accumulated.
• One upstream for a bank looks thin, and for a network this carefully arranged it is the one thing that was not duplicated.
