Summary

Cologne Bonn Airport

Germany · AI-generated

airport business germany

AIRPORT-CGN-AS is operated by Flughafen Koeln/Bonn GmbH.

What it's used for

  • The address space carries internal airport infrastructure, identified by the netname AIRPORT-CGN on both announced IPv4 prefixes.
  • The AS announces 512 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained site network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate and operational systems for the airport, including terminal operations, cargo handling, and facility management.

Notable

  • Registrants for both IPv4 prefixes match the AS holder, Flughafen Koeln/Bonn GmbH, confirming direct ownership of the address space.
  • The address inventory is compact, consisting of two /24 IPv4 blocks and a single /29 IPv6 prefix, typical of a single-site corporate estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, 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: 440 networks and 1,773 prefixes, as published 2026-10-13. 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.
