Summary

Systemnet Networks AS

Norway · AI-generated

business norway small

SYSTEMNET-NO-AS is operated by Systemnet Networks AS, a Norwegian network provider.

What it's used for

  • The address space is registered under the netname HSO-NET with registrant X.25 Holding AS, indicating a corporate or legacy infrastructure estate rather than residential access.
  • The AS announces 1024 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour in RIS. This low neighbour count relative to the address inventory suggests a small, isolated business network or a site-specific internal estate rather than a transit or large-scale access provider.

Notable

  • The RDAP registrant X.25 Holding AS differs from the AS holder Henning Solberg (Systemnet Networks AS), which may reflect historical ownership, a subsidiary relationship, or leased address space.
  • The inventory consists of a single IPv4 prefix 193.201.220.0/22 and a single IPv6 prefix 2001:67c:1ec::/48, representing a compact and unified address block.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-12, 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: 453 networks and 1,848 prefixes, as published 2026-11-12. 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.
