About this network

SYMBION-AS is operated by Symbion A/S.

What it's used for

• The address space carries internal corporate infrastructure for Symbion Science Park, a startup ecosystem and coworking facility in Copenhagen, as indicated by the registrant Symbion A/S and netnames DK-SYMBION-20120531 and DK-SYMBION-20160920.
• The AS announces 3072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained business network rather than a transit or large-scale access provider.
• Traffic from this AS consists of office workers, tenants, and web/API endpoints associated with the Symbion Science Park community and its administrative functions.

Notable

• Registrants for both announced prefixes are Symbion A/S, matching the AS holder and confirming a single-organisation estate.
• The address inventory is compact, consisting of one /21 and one /22 block, consistent with the internal network needs of a specific physical site rather than a distributed ISP footprint.
