isp residential czechia cable

MSTR-AS is operated by Trinity Czech Republic, s.r.o.

What it's used for

  • The address space carries residential and business internet services, evidenced by the netname CZ-MSTR-20110210 and reverse DNS entries such as hh255.mstr.cz and elijah187mhwya.retrodesigners.com.
  • The AS announces 4096 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for optical internet, voice services, and cable television in the Czech Republic.

Notable

  • The registrant TRINITY CZECH REPUBLIC, s.r.o. matches the AS holder, confirming consistent ownership of the address space.
  • The inventory consists of a single /20 IPv4 block and a single /29 IPv6 prefix, representing a compact and focused address allocation for a regional ISP.

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 2026-10-20. 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.
