Summary
Multimedia Polska
cable residential isp poland
MULTIMEDIA-AS is operated by Multimedia Polska Sp. z o.o., a major Polish cable television and internet service provider.
What it's used for
- The address space carries residential customer traffic, evidenced by reverse DNS entries such as
host-81-190-64-0.dynamic.mm.plandhost-89-228-64-0.dynamic.mm.pl. - With 601,344 IPv4 addresses announced across 67 prefixes and only 23 observed neighbours, the high address-to-neighbour ratio indicates an access network serving end-users rather than a transit provider.
Notable
- All sampled registrants are consistent with the announcer, listing
Multimedia Polska Sp. z o.o.andMULTIMEDIA ADMINfor prefixes including81.190.0.0/16and89.228.0.0/16. - The address inventory is large and fragmented, comprising multiple /16, /17, and /18 blocks, which reflects the organic growth of a regional cable operator acquiring space over time.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
