security business czech

The AS handle QRATOR-SW is held by Qrator Labs CZ s.r.o.

What it's used for

  • The address space carries corporate infrastructure for a cybersecurity firm, with the primary netname CZ-QRATOR-20150616 and registrant Qrator Labs CZ s.r.o.
  • The inventory consists of 1792 IPv4 addresses across 4 prefixes and 2 IPv6 prefixes, observed against 1 neighbour, indicating a small, self-contained business network rather than a transit or access provider.
  • Traffic from this AS represents the company's own operational endpoints, including security research infrastructure, web services, and internal office connectivity.

Notable

  • Registrants for the three smaller prefixes (83.147.21.0/24, 151.244.91.0/24, 163.5.133.0/24) are listed as Private Customer, while the largest block is explicitly registered to the company.
  • The address inventory is fragmented into four distinct IPv4 blocks, with the largest being a /22 and the others being /24s, alongside two /32 IPv6 allocations.

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: 447 networks and 1,849 prefixes, as published 2026-10-30. 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.
