Unclassified RIPE
Summary
PRESNET s.r.o.
isp residential slovakia access
PRESNET-AS is operated by PRESNET s.r.o., a Slovak internet service provider based in Prešov.
What it's used for
- The address space carries residential and business customer traffic, evidenced by reverse DNS entries such as
67.18.178.presnet.custand126.73.unitrix.sk, alongside server infrastructure likeserver.pcsat.sk. - The AS announces 7,424 IPv4 addresses across 10 prefixes with only 3 observed routing neighbours, a ratio characteristic of an access network providing last-mile connectivity rather than transit.
- Traffic from this AS consists of subscriber eyeballs and local business endpoints within the Prešov region of Slovakia.
Notable
- Registrants are consistent with the announcer, primarily listing PRESNET s.r.o. and ENERGOTEL a.s. for the 158.255.248.0/22, 158.255.252.0/23, and 158.255.254.0/23 blocks, indicating a corporate relationship or acquisition history.
- The inventory is composed of multiple /23 and /22 blocks, with the largest being 178.18.64.0/21, reflecting a segmented allocation strategy for different customer segments or time periods.

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 2026-10-15, 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 1,782 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.
