Summary

Betrieb fuer Informationstechnologie Bremerhaven

Germany · AI-generated

government municipal it infrastructure

ASN-BIT is operated by Stadt Bremerhaven trading as Betrieb fuer Informationstechnologie Bremerhaven.

What it's used for

  • The address space carries municipal IT infrastructure, identified by netnames DE-BIT-20170519 and BIT-NET-3 registered to the city's IT department.
  • The AS announces 768 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal city government services, administrative endpoints, and municipal IT systems managed by the Bremerhaven IT department.

Notable

  • Registrants align with the announcer, with Stadt Bremerhaven trading as Betrieb fuer Informationstechnologie Bremerhaven listed for the primary prefix and Abuse-C Role for the secondary.
  • The address inventory is compact, consisting of two contiguous IPv4 blocks and a single IPv6 prefix, typical of a municipal internal network.

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.
