Summary
Bank Julius Baer
finance enterprise business
A private bank holding an entire legacy /16 and announcing it as one route.
What it's used for
- The network of a Swiss private bank. 65,536 addresses in the single prefix
159.103.0.0/16, one IPv6 prefix2a06:d581:1000::/36, and three observed BGP neighbours.
Notable
- The netname is
BAERNET, with no country prefix and no date. - The registry holder ends in
AGwhile the registrant on the block ends inLtd. - One IPv4 prefix, one IPv6 prefix, three neighbours.
Interesting
- A whole /16 is space from the era when allocations were sized by the class of the address rather than by need, and a bank that asked for room got sixty-five thousand addresses. It has never been split, which is why the routing table carries one entry for all of it instead of a dozen.
BAERNEThas no date and no country code, which puts it among the oldest naming style in this range: a name that is just a name. Blocks allocated later in this same range carry country prefixes and eight-digit dates because the convention hardened after this one was written.- The legal suffix changes between the holder record and the block record. Both describe the same bank, and the difference is what happens when two entries are created years apart by people copying from different letterheads.
- The IPv6 block is a /36, a fraction of what a provider would take, which fits a network with one organisation behind it rather than customers.

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 2026-10-13, 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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
