Summary

Bank for International Settlements

Switzerland · AI-generated

business financial infrastructure

BIS-AS is operated by Bank for International Settlements (BIS).

What it's used for

  • The address space carries internal corporate infrastructure, as indicated by netnames CH-BIS-NET-20160407 and CH-BIS-NET-19970528 and registrants including BIS-NDC and BIS-ITGOV.
  • The AS announces 1280 IPv4 addresses across 2 prefixes with 2 observed neighbours, a ratio consistent with a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal communications and services for the Bank for International Settlements, an international financial institution owned by central banks and headquartered in Basel, Switzerland.

Notable

  • Registrants align with the announcer, listing Bank for International Settlements (BIS), BIS-NDC, and BIS-ITGOV for both announced prefixes.
  • The address inventory is compact, comprising two distinct IPv4 blocks: 185.146.80.0/22 and 193.135.2.0/24.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, 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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
