AS15904 Hallertau-DE Hallertau.Net e.V.
Unclassified RIPE
Summary
Hallertau.Net
isp telecom business
A registered association running its own number and one block, with a domain name for a company name.
What it's used for
- A member association's network. One IPv4
/24announced from Germany, no IPv6, two hundred and fifty-six addresses, through a single observed BGP neighbour.
Notable
- The holder is a registered association rather than a company, so the network belongs to its members.
- The company name is a region followed by a dot and the abbreviation for a network, which is a domain name used as a legal name.
- The AS handle is that region name with a trailing hyphen and nothing after it, so a suffix was intended and never typed.
- The netname is the same region with the three letters for a network, this time hyphenated in the ordinary way.
- The block lists the association and a contact for abuse, with no role code between them.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- Associations appear in the routing table wherever commercial providers found a region unprofitable. Neighbours pool money, buy transit once, and the legal form that fits is the one used by sports clubs.
- Running an AS number for two hundred and fifty-six addresses is more paperwork than a small network needs, until the alternative is renumbering every time the association changes providers.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-07, 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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
