Residential RIPE
Summary
CSMNP
residential isp cable dsl
The AS handle CSMNP-AS is held by Czestochowska Spoldzielnia Mieszkaniowa "Nasza Praca".
What it's used for
- The address space carries residential broadband traffic, evidenced by reverse DNS entries such as
host-85-202-155-254.sta.tvknaszapraca.plandhost-178-216-90-0.sta.tvknaszapraca.pl. - The network announces 7,168 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with 11 observed neighbours, indicating a regional access provider rather than a transit carrier.
- Traffic consists of subscriber eyeballs for cable and DSL services in the Czestochowa region of Poland.
Notable
- All registrants for the announced prefixes are consistent with the announcer, listing "CSMNP Administrators" and "Czestochowska Spoldzielnia Mieszkaniowa 'Nasza Praca'".
- The address inventory is composed of three distinct IPv4 blocks: 85.202.144.0/20, 178.216.88.0/21, and 185.46.104.0/22.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 443 networks and 1,779 prefixes, as published 2026-10-25. 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.
