Summary

Forschungsverbund Berlin e.V.

Germany · AI-generated

research corporate leibniz berlin

FVB is the autonomous system for Forschungsverbund Berlin e.V., a Berlin-based research alliance.

What it's used for

  • The space carries the internal network of the Berlin Research Alliance, as indicated by the netname DE-ATRIUM-20020305 and the registrant Forschungsverbund Berlin e.V.
  • The AS announces 8192 IPv4 addresses across 1 prefix with only 1 observed neighbour, a ratio that implies an internal corporate estate rather than a transit or access provider.

Notable

  • The RDAP registrant Forschungsverbund Berlin e.V. matches the AS holder, confirming the space is owned by the research alliance itself.
  • The address inventory consists of a single /19 block (62.141.160.0/19), representing a finely subdivided internal network for the alliance's institutes.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
