About this network

Every address in a subnet answers to one name: the address with its last octet removed and the rest reversed.

What it's used for

• A commercial bank's network. Six IPv4 prefixes announced from Ukraine, no IPv6, two thousand and forty-eight addresses, across eleven observed BGP neighbours.

Notable

• All eighteen sampled addresses answer. The name is three octets in reverse order followed by the bank's domain, with the final octet dropped entirely.
• Two addresses in the same subnet therefore return the identical name, which is what the sample shows repeatedly.
• Four of the six blocks carry netnames built from the word for a network and the block's first three octets, joined by underscores rather than hyphens.
• Those four list only an abuse role. The bank appears on the two blocks that use a country code, the brand and an allocation date.
• All six blocks are pieces of one range, announced separately, with the covering block never announced.

Interesting

• A reverse name that identifies the subnet rather than the host is a wildcard by construction. It confirms which network an address belongs to and can never tell two machines apart, which for a bank is closer to a feature than a defect.
• Underscores in a netname are unusual and turn up more than once in this stretch of numbers. They are legal in the registry and illegal in the hostnames these names often get copied into.
