Summary
Open Line
business managed-services it
OPENLINE-AS is operated by Open Line BV.
What it's used for
- The address space carries managed IT infrastructure and corporate services, evidenced by netnames such as
NL-OPENLINE-20071227,OL-MDQ(associated with Mediq BV), andNL-DAMECON-20160503(associated with Conscia Nederland B.V.). - The AS announces 7168 IPv4 addresses across 7 prefixes and 4 IPv6 prefixes, while maintaining 52 observed neighbours; this ratio of moderate address space against a high number of peering partners indicates a transit or managed service provider role rather than a pure access network.
- Traffic from this AS consists of web/API endpoints, office workers, and managed infrastructure for clients in the IT, e-Health, and cloud sectors, reflecting Open Line's business as an IT consultancy and managed services firm.
Notable
- Registrants for the majority of prefixes align with the announcer, listing "Open Line Hostmaster Role" and "Open Line BV", though specific blocks are registered to clients or partners like Mediq BV and Conscia Nederland B.V.
- The address inventory is a mix of /21, /22, /23, and /24 blocks, with some space registered under client-specific netnames like
CONSCIA-NLandOL-MDQ, indicating a model where the provider manages IP space on behalf of its customers.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
