Summary

KVADOS

Czechia · AI-generated

business software czech

KVADOS is held by KVADOS, a.s.

What it's used for

  • The space carries corporate infrastructure, evidenced by the netname CZ-KVADOS-20091222 and registrant KVADOS, a.s.; IT Department.
  • The AS announces 2048 IPv4 addresses and 1 IPv6 prefix with only 2 observed neighbours, indicating a small-scale internal corporate estate rather than a transit or access network.
  • Traffic consists of office workers and internal web/API endpoints for a software development company headquartered in Ostrava.

Notable

  • The registrant KVADOS, a.s.; IT Department aligns directly with the AS holder.
  • The company was originally named HANAS and rebranded to KVADOS in 1993.
  • The address inventory consists of a single /21 block and one /32 IPv6 prefix, consistent with a segmented internal corporate network.

Reputation

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 2026-10-17. 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.
