Summary
MSK-IX
exchange infrastructure russia dns
RIPN-NS5-RU-MSK is operated by MSK-IX (Joint-stock company "Internet Exchange" MSK-IX).
What it's used for
- The address space carries infrastructure for the Moscow Internet Exchange, with netnames including
RIPN-MSK-NET,RU-MSK-IX-19970616,RIPNDNS-RESOLVER, andr-dns. - The AS announces 3072 IPv4 addresses across 11 prefixes and 10 IPv6 prefixes, while maintaining 25 observed neighbours, indicating a role focused on exchange infrastructure and peering rather than mass residential access.
- Traffic from this AS consists of exchange peering sessions, DNS resolver services, and internal network management for the MSK-IX platform.
Notable
- Registrants consistently identify the holder as "Join-stock company 'Internet Exchange' MSK-IX" or "MSK-IX NOC", aligning with the AS handle and announced prefixes.
- The inventory is finely subdivided into multiple /24 blocks and /48 IPv6 prefixes, reflecting site-by-site segmentation typical of a large exchange operator managing distinct service segments.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
