Unclassified RIPE
Summary
Bank J. Safra Sarasin
finance enterprise business
Sixty-five thousand addresses, one route, and no abuse contact listed anywhere.
What it's used for
- A private bank's network. One IPv4
/16announced from Switzerland, no IPv6, sixty-five thousand addresses, across two observed BGP neighbours.
Notable
- The block lists exactly one registrant, the bank's own technology department, with no abuse role at all.
- The netname is a seven-letter contraction of one half of the bank's name, from before the merger that produced the current one.
- The whole holding is a single
/16, announced complete, with no more specific pieces. - Two neighbours carry all sixty-five thousand addresses.
- Three addresses were queried for reverse DNS and none returned a name.
- No IPv6 is announced.
Interesting
- No abuse contact means a complaint has nowhere obvious to go. For a network that hosts nothing public that is a small risk, and it is still a gap in a record that exists to be contactable.
- A contraction of a predecessor bank's name has outlasted the merger in the one field nobody has to update. The holder name changed; the netname did not.
- Two banks in this number range hold a whole
/16each and announce it as one route. Both date from when a large institution could simply ask for one.

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 2026-11-03, 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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
