AS15589 — ASN-CLOUDITALIA

Network type: residential

AS15589 announces 5 IPv4 prefixes covering 3,840 addresses and 0 IPv6 prefixes.

About this network

Five blocks carry five different company identities, and none of them is the holder's.

What it's used for

• A provider's network. Five IPv4 prefixes announced from Italy, no IPv6, three thousand eight hundred addresses, across eight observed BGP neighbours.

Notable

• The holder record names one company, the AS handle names a different brand, two blocks name a third, one names a fourth, and one is registered to an individual rather than a company at all.
• Every answering address sits under the third company's domain, so the reverse DNS follows the netname rather than the holder.
• Names are built from the third and fourth octets joined by a hyphen.
• Two answering addresses end in zero and three end in the last value of their range, so the first and last address of several blocks are named like any other host.
• One block's registry lookup failed. Fifteen addresses were queried for reverse DNS and nine returned a name.

Interesting

• One name stands out from the pattern: a host labelled as a firewall, under a short word that reads as a customer's name. It is the only address in the sample that says what the machine does.
• Naming the network and broadcast addresses of a range is harmless and slightly revealing, since it confirms where each block's boundaries fall without any probing.
• Nine names from fifteen addresses is a high answer rate for this size of network, and all nine point at the same acquired brand.
