Summary
RBNet (Russian Backbone Network) / MSK-IX
research education legacy
RBNet is the Russian Backbone Network, the interdepartmental backbone that connects Russia's regional science and education networks. It was built by RIPN (RosNIIROS, the Russian Institute for Public Networks) and is registered today to the joint-stock company behind MSK-IX.
What it's used for
- Backbone transit between regional research and education networks, with nodes spread across Russia's federal districts, rather than direct end-user access.
- The holder also operates MSK-IX, Russia's principal internet exchange, so this AS sits alongside exchange-point infrastructure rather than a commercial customer base.
Notable
- RIPN was the organisation that both ran the academic backbone and founded the Moscow exchange, an unusually direct link between a country's research network and its main peering fabric.
- The announced footprint is small for a backbone. That is expected: a transit AS for other networks carries routes, not large pools of its own addresses.

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: 442 networks and 1,783 prefixes, as published 2026-10-20. 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.
