Summary

JN DATA A/S

Denmark · AI-generated

business financial infrastructure

JNDATA-AS is operated by JN DATA A/S.

What it's used for

  • The address space carries infrastructure for financial services, evidenced by netnames DK-BEC-NET registered to BEC Financial Technologies a.m.b.a. and ORG-FB159-RIPE associated with Foreningen Bankdata.
  • The AS announces 8,448 IPv4 addresses across 6 prefixes with 4 observed neighbours, indicating a business network with limited peering rather than a transit provider.
  • Traffic consists of internal corporate and financial institution endpoints, supporting banking and payment processing operations.

Notable

  • Registrants align with the announcer for most prefixes, though DK-BEC-NET prefixes are registered to BEC Financial Technologies a.m.b.a., indicating a distinct legal entity within the same operational group.
  • The inventory is finely subdivided into six small blocks, consistent with an internal corporate estate segmented by function or site.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, 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: 445 networks and 1,817 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.
