Unclassified RIPE
Summary
AB-NET
isp residential czech access
AB-NET is operated by AB-NET s.r.o.
What it's used for
- The address space carries residential customer traffic, evidenced by the reverse DNS record
254F.customer.trinity.czassociated with the188.95.56.0/21block. - The AS announces 3072 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, maintaining only 2 observed neighbours, a ratio indicative of an access network rather than a transit provider.
- As a Czech internet service provider, the traffic consists of subscriber eyeballs accessing the internet via fixed-line connections.
Notable
- Registrants for both announced IPv4 prefixes (
CZ-ABNET-20090623andCZ-ABNET-20150219) are listed as AB-NET s.r.o., consistent with the AS holder. - The address inventory is compact, comprising two distinct IPv4 blocks and a single IPv6 /32 prefix.

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 2026-10-16, 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 1,783 prefixes, as published 2026-10-17. 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.
