Summary

AIT LLC

Russian Federation · AI-generated

business russia small

The AS handle MSMR-AS is held by AIT LLC.

What it's used for

  • The space carries a single IPv4 prefix, 91.224.233.0/24, with the netname RU-MSMR and registrant AIT LLC.
  • The inventory consists of 256 IPv4 addresses across 1 prefix, with 0 IPv6 prefixes announced.
  • With 2 observed neighbours, the low neighbour count relative to the address space suggests a small-scale access or internal network rather than a transit provider.

Notable

  • The RDAP registrant AIT LLC matches the registry holder MSMR-AS AIT LLC, confirming consistent ownership.
  • The address inventory is minimal, consisting of a single /24 block, indicating a small operational footprint.

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 1,782 prefixes, as published 2026-10-16. 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.
