Summary

CETIN a.s.

Czechia · AI-generated

isp residential czechia cable

M-NET is operated by CETIN a.s.

What it's used for

  • The space carries residential and business access traffic, evidenced by the netname CZ-CETIN-20100108 and reverse DNS entries like 255-95-224-109.m-zone.cz.
  • The AS announces 16,384 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with only 1 observed neighbour, indicating a regional access provider rather than a transit hub.
  • Traffic consists of subscriber eyeballs for cable and DSL services in the Czech Republic, consistent with the operator's role as a regional ISP.

Notable

  • Registrants align with the announcer, listing CETIN a.s. and CETIN hostmaster for the primary prefix.
  • The address inventory is a single contiguous /18 block, typical of a regional ISP managing its own allocated space.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
