Summary

CTI Systems

Ukraine · AI-generated

business ukraine small

The AS handle CTISYSTEMS-AS is held by CTI Systems.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname CTI-NET and reverse DNS entries pointing to cti.net.ua.
  • The inventory consists of 512 IPv4 addresses within a single prefix (195.26.84.0/23) and 0 IPv6 prefixes.
  • With only 2 observed neighbours, the low neighbour count relative to the address block suggests a small-scale business or internal corporate network rather than a transit provider or large access network.

Notable

  • The RDAP registrant LTD "CTI Systems" matches the AS holder, confirming consistent ownership of the announced space.
  • The address inventory is compact, comprising a single /23 block in Ukraine, with no IPv6 allocation in the current inventory.

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: 448 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.
