Summary

Oles Honchar Dnipro National University

Ukraine · AI-generated

education university legacy

Oles Honchar Dnipro National University (DSU-AS) — the classical university in Dnipro, Ukraine, founded in 1918. A single legacy /24 and a single BGP neighbour: the whole AS is one campus network.

What it's used for

  • Campus connectivity for the university's faculties, labs and administration. The rDNS is a plain sequential campus scheme, hostNNN.dsu.dp.ua, with the occasional named departmental host (for example the mechanics-and-mathematics faculty's server).
  • The dsu.dp.ua domain preserves the university's earlier name, Dnipropetrovsk State University, which is also what the RIPE handle records.

Notable

  • 256 addresses is about as small as a routed AS gets. Universities of this vintage typically hold a legacy /24 from the mid-1990s academic build-out and never needed more, because everything behind it is NATed.
  • Single-homed: one upstream, no peering. The AS exists so the university can keep its own address block portable across providers, not to carry transit.

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.

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.
