Summary

Chaos Computer Club Veranstaltungsgesellschaft

Germany · AI-generated

isp infrastructure business

A reverse zone that writes addresses in hexadecimal, on a /19 that only lights up for events.

What it's used for

  • The event network of the Chaos Computer Club's events company. 8,192 addresses in one IPv4 prefix, one IPv6 prefix, and one observed BGP neighbour.

Notable

  • The blocks are 94.45.224.0/19, netname CCC-EVENT-NET, and 2001:67c:20a1::/48.
  • All three sampled addresses answered, under eventnet.ccc.de.
  • The names are hexadecimal: 94.45.232.0 answers e800, 94.45.239.255 answers efff, and 94.45.247.254 answers f7fe.

Interesting

  • Each name is the last two octets written as four hex digits, so 232 and 0 become e800. Every other generated zone in this sweep writes addresses in decimal, usually with the dots turned into hyphens. Hex is the form an engineer reads a network in rather than the form a customer does, and choosing it says who the zone was written for.
  • A /19 and a /48 held by an events company is address space that sits idle most of the year and then has to number a congress hall in an afternoon. Permanent allocations for temporary networks make sense once you notice the alternative is renumbering the entire operation annually.
  • The IPv6 /48 comes from 2001:67c::/32, the same parent as the assignment on AS13008 in this range. That block is handed out as provider-independent space, so a /48 from it marks address space that stays with the holder across any change of upstream.
  • One neighbour, which is all a network needs when it exists to be reachable rather than to sell reach.

Reputation

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
