Unclassified RIPE
Summary
National Bank of Greece
enterprise legacy
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
195.78.86.0/23allocation.
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.

Interconnection

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-07, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 454 networks and 1,852 prefixes, as published 2026-11-08. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
