Summary

Stadt Köln

Germany · AI-generated

government municipal network

STADTKOELN1 is operated by Stadt Köln, the municipal government of Cologne.

What it's used for

  • The address space carries municipal network infrastructure, identified by the netname CAN-MAN and registrant Stadt Koeln.
  • The AS announces 16,384 IPv4 addresses within a single /18 prefix (193.27.128.0/18) and one IPv6 /48 prefix, with only one observed routing neighbour.
  • This low neighbour count relative to the address inventory indicates an internal corporate estate for city administration, not a transit or access provider.

Notable

  • The RDAP registrant Stadt Koeln and the AS handle StadtKoeln1 align directly with the operator's identity.
  • The inventory consists of a single contiguous IPv4 block and one IPv6 prefix, consistent with a segmented internal network for a large municipal entity.

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.
