Unclassified RIPE
Summary
ING Bank
finance enterprise business infrastructure
Two ranges are announced whole, in twenty pieces, with nothing left over.
What it's used for
- A bank's network. Twenty IPv4 prefixes announced from the Netherlands, no IPv6, eighty-one thousand addresses, across four observed BGP neighbours.
Notable
- Eleven routes tile one range completely, from a
/17down through a/24, covering every address in it with no gaps and no overlaps. - Nine more routes do the same to a second, smaller range, again exactly and again in pieces of four different sizes.
- Every block carries the identical netname naming the banking group, so the registry cannot tell the pieces apart at all.
- One block's registry lookup failed, so its details are unknown rather than absent.
- Four neighbours carry eighty-one thousand addresses.
- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- Announcing every piece of a range separately when the range itself would do is a choice made somewhere inside the bank, and it costs the rest of the internet nineteen extra routing entries.
- The arithmetic is exact in both ranges, which means the split follows an internal plan rather than accumulated history. Someone drew this map on purpose.
- Eighty-one thousand addresses with no IPv6 and nothing answering in reverse is a network built for internal use, where the addresses are inventory rather than a public presence.

Interconnection
Peering at a glance
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 2026-11-06, 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 1,854 prefixes, as published 2026-11-06. 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.
