Summary

Netvaerkssmeden

Denmark · AI-generated

isp residential denmark regional

NETVAERKSSMEDEN is operated by James Hansen trading as Netvaerkssmeden.

What it's used for

  • The address space carries mixed customer and corporate allocations, including netnames CORE-NET1, SpejdernesLejr2026, BONNIERDK, and BONNONLINEDK.
  • The AS announces 3072 IPv4 addresses across 5 prefixes and 2 IPv6 prefixes, with only 3 observed neighbours, indicating a small regional access network rather than a transit provider.
  • As a regional cable/DSL ISP, the traffic consists of subscriber eyeballs and local business endpoints, including specific allocations for Bonnier Publications A/S.

Notable

  • Registrants vary by prefix: James Hansen trading as Netvaerkssmeden holds the largest block and the scout camp allocation, while Dynado ApS and Bonnier Publications A/S hold separate /24 blocks.
  • The inventory is fragmented, with the largest prefix being a /21 and the rest being /24s, reflecting a collection of distinct customer or service allocations rather than a single contiguous estate.

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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
