Unclassified RIPE
Summary
Hamburger Hochbahn AG
transport municipal infrastructure germany
The AS handle HAMBURGER_HOCHBAHN is held by Hamburger Hochbahn AG.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by the netname
NETUSE-HHA-08associated with the single announced prefix. - The AS announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
- Traffic from this AS consists of internal data for the operator's public transport systems, including subway and bus network management, signalling, and administrative functions.
Notable
- The RDAP registrant for the prefix is
Role-Account NetUSE AG Abuse Department, which differs from the AS holder, suggesting the address space is managed or leased through NetUSE AG. - Hamburger Hochbahn AG is a government-related entity of the State of Hamburg, operating the city's underground system and large parts of its bus network.
- The address inventory consists of a single /24 block, reflecting a minimal footprint typical of a specific operational segment within a larger municipal transport authority.

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 2026-10-25, 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 1,779 prefixes, as published 2026-10-24. 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.
