Sweden · AI-generated

residential fiber isp sweden

The AS handle LYSSNA-NJUT-AB is held by Lyssna & Njut Fibernet AB.

What it's used for

  • The address space carries residential fiber-to-the-home traffic, evidenced by reverse DNS entries such as pon-fiber.lnctv.com and cable-cust.lnctv.com.
  • The network announces 5120 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio that indicates an access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for a local fiber internet service provider operating in Balsta, Sweden.

Notable

  • Both announced prefixes, 77.244.0.0/20 and 185.212.24.0/22, list Lyssna & Njut Fibernet AB as the registrant, matching the AS holder.
  • The address inventory is composed of two distinct IPv4 blocks with no IPv6 prefixes in the inventory.

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 1,849 prefixes, as published 2026-10-29. 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.
