Unclassified APNIC
Summary
Cukman Kresimir
business croatia small
The AS handle CUKMAN-AS is held by Cukman Kresimir.
What it's used for
- The address space carries business traffic, indicated by the reverse DNS entries pointing to
ptr.potenting.comfor the 85.158.145.0/24 block. - The network announces 512 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, suggesting a small-scale access or endpoint network rather than a transit provider.
- Traffic from this AS consists of web endpoints and business services associated with the Potenting brand, as evidenced by the PTR records.
Notable
- Registrants do not fully align with the announcer; the 85.158.145.0/24 block is registered to "Customer of Simurgh" with netname
cukman-kresimir, while the 193.124.207.0/24 block is registered to "Reliable Communications s.r.o." with netnameCZ-RELCOM-19930901. - The inventory includes a mix of blocks with different registrant histories, including one associated with a Czech company, indicating potential leased space or historical acquisitions.

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 2026-10-27, 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.
