Summary
Chaos Computer Club Darmstadt
nonprofit legacy
CCCDA belongs to Chaos Computer Club Darmstadt e.V., the Darmstadt chapter of the Chaos Computer Club, Europe's largest hacker association.
What it's used for
- Club infrastructure and experimentation. The chapter is a registered non-profit association (
e.V.) with premises on Wilhelminenstrasse in Darmstadt. - The network is IPv6-only in practice: a single
/48is announced and there is no IPv4 in the routing table at all.
Notable
- The
/48comes out of2001:67c::/32, the RIPE NCC's special-assignment range used for allocations to organisations such as clubs, projects and other non-commercial entities. - Announcing no IPv4 whatsoever is unusual even among hobbyist and community networks, and fits the club's habit of running v6-native infrastructure as a matter of principle.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, 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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
