About this network

One netname says outright that the block carries the card systems.

What it's used for

• A bank's network. Four IPv4 prefixes announced from Greece, no IPv6, two and a half thousand addresses, through one observed BGP neighbour.

Notable

• Three netnames use a merged bank's initials and its name, one of them with a counter appended, and the fourth replaces all of that with the word cards.
• Every registrant field names the bank under its current shorter name and an abuse role that still carries the older combined one.
• The four blocks come from four unrelated parts of the address space.
• Twelve addresses were queried for reverse DNS and none returned a name.
• One observed neighbour for a bank of this size.

Interesting

• Labelling a block as card infrastructure in a public registry narrows the search for anyone interested in payment systems. It is convenient internally and free information externally.
• The initials that survive in the netnames are from a merger the bank's own name no longer mentions, which makes the registry a record of corporate history nobody chose to publish.
• A single upstream is the entry worth questioning. A bank that cannot reach the internet cannot run card authorisation, and one path is one failure.
