isp cable fiber residential

COSYS is operated by COSYS DATA GmbH.

What it's used for

  • The address space carries residential broadband traffic, evidenced by the reverse DNS record 254.50.57.2.dynip.cosys.cc and netnames such as AT-COSYSDATA-20190318.
  • The AS announces 4096 IPv4 addresses across 7 prefixes and 4 IPv6 prefixes, with 29 observed neighbours, indicating a regional access network providing last-mile connectivity.
  • Traffic consists of subscriber eyeballs for internet, cable, and fiber services delivered to households in Upper Austria.

Notable

  • All registrants for the announced prefixes are listed as COSYS DATA GmbH, matching the AS holder.
  • The address inventory is subdivided into multiple /22 and /24 blocks, reflecting the expansion of the company's cable and fiber infrastructure since its founding in 2016.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
