Summary

OSSO

Netherlands · AI-generated

hosting business netherlands

OSSO is operated by OSSO B.V.

What it's used for

  • The address space carries hosting and network infrastructure, evidenced by reverse DNS entries like osso.network and osso.nl, and netnames such as NL-OSSOBV-20090327 and OSSO-OSPF-LB.
  • With 9,728 IPv4 addresses announced across 12 prefixes and 117 observed neighbours, the ratio indicates a transit or peering-heavy role rather than a large residential access network.
  • Traffic from this AS consists of web/API endpoints, cloud infrastructure, and network engineering services, as OSSO specializes in open source hosting, network, and cloud infrastructure development and operations.

Notable

  • Registrants largely agree with the announcer, with most prefixes registered to OSSO B.V. or OSSO NOC, though some blocks are registered to Exception B.V. and Ark B Holding B.V..
  • The address inventory is finely subdivided into multiple /22 and /23 blocks, consistent with an internal corporate estate or segmented hosting infrastructure rather than a single contiguous allocation.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
