Summary

Breitband in Bayern

Germany · AI-generated

residential fiber municipal germany

BIB is the autonomous system for Breitband in Bayern GmbH.

What it's used for

  • The address space carries residential broadband traffic, evidenced by the netname DE-BIB-20210518 and the registrant Breitband in Bayern NOC.
  • The AS announces 512 IPv4 addresses and 1 IPv6 prefix, with a single observed neighbour, indicating a leaf access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for high-speed internet access, specifically supporting the gigabit-capable broadband infrastructure in the Lohr a.Main region.

Notable

  • The registrant Breitband in Bayern NOC aligns directly with the AS holder Breitband in Bayern GmbH.
  • The address inventory is compact, consisting of a single /23 IPv4 block and a /48 IPv6 block, typical for a regional municipal broadband project.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-03, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,851 prefixes, as published 2026-11-04. 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.
