Summary

OBT AG

Switzerland · AI-generated

business corporate switzerland

OBT-AG is held by OBT AG.

What it's used for

  • The address space carries corporate infrastructure, evidenced by netnames CH-OBT-20190924 and CH-OBT-20160614 registered to OBT AG.
  • The AS announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining 43 observed neighbours; this ratio of limited address space against a high neighbour count indicates a transit or peering-heavy role rather than a large access network.
  • Traffic from this AS consists of office workers and internal IT endpoints for a Swiss fiduciary, auditing, and consulting firm with approximately 300 employees across 12 offices.

Notable

  • Registrants for both announced IPv4 prefixes are listed as OBT AG, agreeing with the AS holder.
  • The address inventory is small and finely subdivided into two /22 blocks, consistent with an internal corporate estate segmented by site or function rather than a public-facing service provider.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-04, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
