Summary

Symbion A/S

Denmark · AI-generated

business real-estate cph

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.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
