About this network

NATIONAL-BANK-OF-GREECE is the network of National Bank of Greece S.A., one of the country's largest banks.

What it's used for

• The bank's own enterprise connectivity: branch, corporate and customer-facing banking systems.
• A deliberately small footprint — around 512 IPv4 addresses, all from a single 195.78.86.0/23 allocation.

Notable

• A textbook enterprise AS. Banks run their own AS number so they can multihome across several carriers and keep control of routing for services that cannot go offline; they have no reason to hold large address space.
• No public reverse DNS is published on its ranges, which is typical for a financial institution keeping its infrastructure unadvertised.

Interesting

• The RIPE object is maintained under a Greek ISP's maintainer handle, a common arrangement where a bank's provider administers the registry objects on its behalf while the bank remains the registered holder.
