AS49025 PROZETA-NET
Unclassified RIPE
Summary
PRO-ZETA
business hosting it-services
The AS handle PROZETA-NET is held by PRO-ZETA a.s.
What it's used for
- The address space carries corporate infrastructure, evidenced by reverse DNS entries like
128-214.prozeta.netand netnames such asCZ-PROZETA-20090310. - With 3072 IPv4 addresses announced across 7 prefixes and 30 observed neighbours, the ratio suggests a business network with moderate peering rather than a large-scale residential access provider.
- As a Czech technology company providing managed OpenStack cloud, Arista distribution, and IT services, the traffic consists of enterprise clients, cloud workloads, and internal corporate endpoints.
Notable
- All registrants for the largest prefixes are listed as PRO-ZETA a.s., consistent with the AS holder.
- The address inventory is composed of multiple /24 and /23 blocks, including a /22, indicating a segmented corporate estate rather than a single contiguous allocation.

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 1,782 prefixes, as published 2026-10-16. 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.
