Summary

Kolding Net

Denmark · AI-generated

isp residential denmark small

The AS handle KOLDINGNET is held by Kolding Net (kolding.net).

What it's used for

  • The space carries residential and local business connectivity in the Kolding area, as indicated by the netname KOLDINGNET and registrant kolding.net.
  • The AS announces 2048 IPv4 addresses in a single /21 prefix (145.11.32.0/21) and one IPv6 prefix (2a12:cd40::/29).
  • With only 1 observed neighbour, the network operates as a small, self-contained access provider rather than a transit hub, serving local subscribers directly.

Notable

  • The RDAP registrant kolding.net matches the AS handle KOLDINGNET and the registry name, confirming consistent ownership.
  • The address inventory consists of a single contiguous IPv4 block and a single IPv6 prefix, typical of a small regional ISP managing its own allocated space.

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 2026-11-09. 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.
