Summary

Norlys Telco

Denmark · AI-generated

residential isp denmark cable

The AS handle SYDFYN is operated by Norlys Telco A/S.

What it's used for

  • The address space carries residential customer traffic, evidenced by reverse DNS entries such as 85-27-191-255.norlyscustomer.net and 85.27.160.0.sydfynsnet.dk.
  • The network announces 32768 IPv4 addresses within a single prefix (85.27.128.0/17) and maintains only 1 observed neighbour, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

  • The RDAP registrant for the announced prefix is listed as "Norlys Telco A/S; Stofa AS" with the netname DK-STOFANET-20050321, reflecting the historical integration of Stofa assets into the Norlys group.
  • Norlys Telco A/S is the result of a 2026 merger between Norlys Mobil A/S and Norlys Digital A/S, consolidating the mobile and digital operations of the Norlys group.
  • The inventory consists of a single contiguous /17 block, representing a finely subdivided internal corporate estate for regional service delivery.

Internet exchanges

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-06, 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 1,854 prefixes, as published 2026-11-06. 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.
