- Traffic from this AS consists of web/API endpoints, mail servers, and cloud workloads for Greenhousing's datacenter and hosting customers in Prague.

Greendata s.r.o.,FIBER Network s.r.o.,CoProSys RIPE Admins, andAK SYSTEM s.r.o., showing a mix of owned and leased or partner-managed address space. - The address inventory is finely subdivided into small /24 and /23 blocks alongside a larger /21, consistent with internal segmentation for different services or customer groups within the datacenter estate.

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 2026-10-30, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
