Summary

Region Västmanland

Sweden · AI-generated

government regional sweden

VASTMANLANDS is held by Region Västmanland.

What it's used for

  • The address space carries regional government infrastructure, evidenced by the registrant Resilans AB and the netname SE-RESILANS-970602.
  • The network announces 1024 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained internal estate rather than a transit or access provider.
  • Traffic from this AS consists of internal administrative and service endpoints for the Västmanland regional authority, including healthcare and public services managed by the region.

Notable

  • The RDAP registrant Resilans AB differs from the AS holder Region Västmanland, reflecting the operational structure where Resilans AB manages IT infrastructure for the region.
  • The inventory consists of a single contiguous IPv4 block 193.180.8.0/22 and one IPv6 prefix 2001:67c:728::/48, representing a finely subdivided internal corporate estate.

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.

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 2026-11-12. 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.
