LEVEL-MSKfor both announced IPv4 prefixes, indicating a single operator's infrastructure. - The AS announces 768 IPv4 addresses and 1 IPv6 prefix, with 48 observed neighbours; this ratio of modest address space to high peering count indicates a regional transit or network service provider role.
- As a regional network service provider (NSP) in Russia, the traffic consists of upstream transit and interconnection for regional subscribers and businesses.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
