Unclassified RIPE
Summary
JYSK
retail corporate internal
The AS handle JYSK is held by JYSK A/S.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by netnames
DK-JYSKandDE-DBL-20110623and registrants consistently listing "JYSK Networking Team" and "JYSK A/S". - The AS announces 4,352 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 4 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
- Traffic from this AS consists of internal corporate systems, store backhaul, and web/API endpoints for the retail chain's operations.
Notable
- Registrants align with the announcer, with all prefixes registered to JYSK entities including "JYSK Networking Team" and "JYSK A/S".
- The address inventory is finely subdivided into four distinct IPv4 blocks, consistent with site-by-site segmentation for a large retail estate.

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 2026-10-26, 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: 446 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.
