Summary

ITS a.s.

Czechia · AI-generated

business transit managed-services

ITS-CZ is operated by ITS a.s., a Czech managed service provider and IT solutions integrator.

What it's used for

  • The address space carries a mix of corporate and third-party netnames, including CZ-ITS-20081125, CZ-FORTUNA-NET (Fortuna Game a.s.), CZ-TESCO-NET (Tesco Stores CR a.s.), and UK-TESCOSIP-20080814 (Tesco Stores Ltd).
  • With 4,608 IPv4 addresses announced across 5 prefixes and 34 observed neighbours, the ratio indicates a transit or peering role rather than a large-scale access network.
  • As an MSP and ISV partner for vendors like IBM, Cisco, and Fortinet, the traffic consists of managed service endpoints, enterprise backhaul, and client infrastructure rather than residential subscriber eyeballs.

Notable

  • Registrants vary significantly across prefixes, with ITS akciova spolecnost holding the largest block, while other blocks are registered to FORTUNA GAME a.s., Tesco Stores CR a.s., and Tesco Stores Ltd.
  • The inventory includes a large IPv6 prefix 2a02:db8::/32 alongside the IPv4 space.
  • The address inventory is fragmented across multiple distinct corporate entities, suggesting a history of acquisitions or managed IP leasing for clients.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
