Unclassified RIPE
Summary
Sentia Denmark
business cloud managed-services denmark
SENTIA is operated by Sentia Denmark A/S.
What it's used for
- The address space is registered under netnames such as
DK-SENTIA-20020131andDK-SENTIA-20050414, with registrants consistently listed as Jaynet Network Operation Center and Sentia Denmark A/S. - The AS announces 110,848 IPv4 addresses across 99 prefixes and 6 IPv6 prefixes, while maintaining only 9 observed routing neighbours. This high address-to-neighbour ratio indicates an access or enterprise network rather than a transit provider.
- Sentia Denmark is an ISO 27001-certified Azure Expert Managed Service Provider offering compliant and managed cloud solutions. Traffic from this AS consists of corporate IT infrastructure, cloud service endpoints, and managed network operations for business clients.
Notable
- Registrant data for the largest prefixes aligns with the AS holder, listing both Jaynet Network Operation Center and Sentia Denmark A/S.
- The address inventory is finely subdivided into numerous /21 and /20 blocks, consistent with an internal corporate estate or managed service provider segmenting space for distinct client or service deployments.

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 2026-10-14, 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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
