Summary

OSISM GmbH

Germany · AI-generated

hosting cloud germany

The AS handle OSISM is held by OSISM GmbH.

What it's used for

  • The address space carries cloud and hosting infrastructure, evidenced by netnames de-betacloud-1-regiocloud-1 and de-betacloud-1-regiocloud-2 and the reverse DNS entry mail.regiocloud.meissner-it.eu.
  • The network announces 768 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small-scale hosting or cloud provider rather than a transit or access network.
  • Traffic from this AS consists of web and API endpoints for cloud services, consistent with OSISM's business as a German cloud and IT services provider.

Notable

  • Registrants for both announced prefixes are OSISM GmbH, matching the AS holder.
  • The address inventory is compact, consisting of two contiguous IPv4 blocks within the 81.163.192.0/23 range and a single /32 IPv6 prefix.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-11, 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: 453 networks and 1,846 prefixes, as published 2026-11-11. 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.
