About this network

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.
