Autonomous system
AS15916 Former Fortis Bank Woerden, Netherlands
Unclassified RIPE
Summary
ABN AMRO Bank
finance enterprise business
The AS handle begins with the word "Former" and names a bank that no longer exists, plus its town.
What it's used for
- A bank's network. Nineteen IPv4 prefixes announced from the Netherlands, no IPv6, sixty-five thousand five hundred and thirty-six addresses, across two observed BGP neighbours.
Notable
- The handle is a sentence rather than an identifier: the word for something that used to be, a vanished bank's name, a town, and a comma before the country.
- Every one of the nineteen prefixes sits inside the same
/17, which is also announced whole, so the network advertises one range and eighteen pieces of it at the same time. - The pieces run from a
/19down to a/24and cover only part of the range, so the split follows something internal rather than a plan to cover everything. - One block's registry lookup failed, so its details are unknown rather than absent.
- Every readable block carries the same netname and the same two contacts, the second an abbreviation followed by the word for infrastructure.
- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- Announcing a range and its pieces together lets each piece take a different path while the whole keeps working if a piece is withdrawn. For a bank spanning many sites on one range, that is how traffic gets pinned to the right data centre.
- A handle recording an acquisition is the most honest field in the record, and the only one anyone updated.

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 2026-10-25, 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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
