Summary

Bolignet-Aarhus

Denmark · AI-generated

non-profit residential denmark access

The AS handle BNAA-AS is held by Bolignet-Aarhus F.M.B.A., a non-profit housing association network in Denmark.

What it's used for

  • The address space carries residential and housing-related traffic, evidenced by the netname AL2NET registered to Al2Bolig Forening and reverse DNS pointers like 84-238-95-254.ptr.bnaa.dk.
  • The network announces 35328 IPv4 addresses across 4 prefixes while maintaining only 1 observed neighbour, a ratio that indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants for the two smaller prefixes (194.28.24.0/22 and 194.8.242.0/23) are listed as Al2Bolig Forening, while the larger blocks are registered to BOLIGNET-AARHUS F.M.B.A., suggesting a relationship between the housing association and the network operator.
  • The inventory consists of one large /17 block and three smaller /22 and /23 blocks, all located in Denmark.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, 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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
