Residential RIPE
Summary
Telefon Serwis
isp residential fiber poland
The AS handle TELEFONSERWIS-AS is held by Telefon Serwis (Zakład Teleradiotechniki Telefon Serwis Antoni Kois).
What it's used for
- The address space carries residential fiber-to-the-home traffic, as indicated by reverse DNS entries such as
91-224-118-128.fttx.telefonserwis.pland91-197-241-64.fttx.telefonserwis.pl. - The network announces 1024 IPv4 addresses across 3 prefixes and maintains 4 observed neighbours, a ratio consistent with a local access provider rather than a transit carrier.
- Traffic originates from subscriber endpoints connected via the operator's fiber infrastructure in the Jasło region of Poland.
Notable
- All registrants for the announced prefixes are listed as Antoni Kois, matching the AS holder name.
- The inventory consists of three distinct IPv4 blocks: 91.224.118.0/23, 91.197.241.0/24, and 91.231.125.0/24, all located in Poland.

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 2026-10-17, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
