Summary

Ljusnet

Sweden · AI-generated

residential isp sweden fiber

The AS handle LJUSNET-AS is operated by Ljusnet AB.

What it's used for

  • The address space carries residential and business internet services, evidenced by reverse DNS entries such as 87-249-168-0.ljusnet.se and 80-65-196-0.ljusnet.se.
  • With 12,544 IPv4 addresses announced across 3 prefixes and only 1 observed neighbour, the network functions as an access provider rather than a transit carrier.

Notable

  • Registrants for the two largest prefixes (87.249.160.0/19 and 80.65.192.0/20) are listed as Ljusnet Registry and Ljusnet AB, consistent with the announcer.
  • The smaller prefix 194.103.35.0/24 is registered to Ljusdals kommun, indicating municipal ownership or a specific local government allocation within the AS.
  • The inventory includes a large IPv6 block 2001:1660::/32 alongside a smaller 2001:67c:266c::/48, suggesting a mix of legacy and modern address space management.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-21, 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: 442 networks and 1,779 prefixes, as published 2026-10-22. 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.
