Summary
Zenon N.S.P. / Astra Cloud
hosting legacy
ZENON-AS is the network of Zenon N.S.P., one of Russia's oldest hosting providers, based in Moscow. The ASN is now registered to LLC "ASTRA CLOUD" following a chain of acquisitions.
What it's used for
- Shared hosting, virtual private servers, dedicated servers, and colocation in Moscow. Reverse DNS across the announced space makes this plain: hostnames resolve as
zvps…host.ru,zvm…host.ru, and…distributed.zenon.net, and a scattering of customer domains resolve directly on the space. - Roughly 10k IPv4 addresses across a couple of dozen prefixes, chiefly within
195.2.64.0/18and213.189.192.0/18.
Notable
- This is a hosting provider, not an access ISP. There are no subscriber pools in the reverse DNS, only server naming.
- The ownership trail is visible in the registry: the maintainer is
MNT-RUSONYX(Rusonyx acquired Zenon in 2019), while the organisation record now reads LLC "ASTRA CLOUD" after Astra Group took a controlling stake in Rusonyx. TheZENON-AShandle survives all of it.
Interesting
- Zenon was founded in the mid-1990s, which puts it among the first generation of Russian commercial internet businesses. The brand outlived two changes of owner and is still the name attached to this AS.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
