About this network

BLIX is operated by Blix Solutions AS.

What it's used for

• The address space carries a mix of Blix Group infrastructure and acquired or leased blocks, with netnames including NO-BLIXGROUP, NO-OPENNET, NO-UPPERCASE, HOST1-CNET, UK-FASTPLANET, NO-DIRA, and NO-RASKESIDER.
• The AS announces 40,192 IPv4 addresses across 82 prefixes and 129 IPv6 prefixes, while maintaining 914 observed neighbours; this high neighbour-to-address ratio indicates a transit and network service provider role rather than a pure access network.
• Traffic from this AS consists of data center hosting, co-location, and ISP services, with Blix Solutions operating data centers in Oslo, Stockholm, Copenhagen, Helsinki, Amsterdam, and London.

Notable

• Registrants for the largest prefixes are predominantly Blix Group AS, though several blocks are registered to other entities such as UPPERCASE AS, Host1 AS, FASTPLANET LTD, Digital Raadgivning AS, and Servebolt AS, reflecting historical acquisitions or leased space.
• The address inventory is fragmented across multiple /21, /22, and /23 blocks, with a significant portion of the IPv6 space concentrated under the 2a02:20c8::/35 range.
