Summary

Chernihiv State Technological University

Ukraine · AI-generated

education university ukraine

The AS handle CSTU-AS is held by Chernihiv State Technological University.

What it's used for

  • The address space carries university infrastructure, evidenced by the netname CINET-NOC and the registrant identity.
  • The network announces 256 IPv4 addresses across 1 prefix with 1 observed neighbour, indicating a small, self-contained institutional network rather than a transit or large access provider.

Notable

  • The RDAP registrant matches the AS holder, confirming the space is directly owned by the university.
  • The inventory consists of a single /24 block, representing a compact and stable address allocation for the institution.

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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
