Summary

Västra Götalandsregionen

Sweden · AI-generated

government healthcare regional sweden

VASTRAGOTALANDSREGIONEN is operated by Västra Götalandsregionen, the regional government of western Sweden.

What it's used for

  • The address space carries internal networks for regional healthcare and administration, evidenced by netnames such as ALVSBORGNET, NET-BOHUSNET, GSV-NET, GSVLAN01, SE-SKAS-NET (Skaraborgs sjukhus), and SE-BASLID.
  • The AS announces 203,776 IPv4 addresses across 13 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a self-contained internal corporate estate rather than a transit or access network.
  • Traffic consists of office workers, hospital staff, and administrative endpoints within the regional government's infrastructure.

Notable

  • Registrants largely align with the announcer, with most prefixes registered to "Vastra Gotalandsregionen; VGR Hostmaster", while 192.71.66.0/23 is registered to Resilans AB and 192.71.14.0/24 and 192.71.139.0/24 to Skaraborgs sjukhus.
  • The inventory is finely subdivided into site-specific /23 and /24 blocks alongside larger /16 allocations, reflecting a segmented internal network design.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-03, 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: 448 networks and 1,851 prefixes, as published 2026-11-04. 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.
