Summary
Informational-measuring systems Ltd.
business russia ims
The AS handle ASN-IMSYS is held by Informational-measuring systems Ltd.
What it's used for
- The address space is registered under netnames such as
RU-IMSYS,RU-IMSYS-3, andRU-IMSYS-COLLOCATION, indicating a corporate infrastructure estate. - The AS announces 7680 IPv4 addresses across 8 prefixes and maintains 20 observed neighbours, a ratio consistent with a business network rather than a transit provider.
Notable
- Registrants for all listed prefixes are consistent with the announcer, listing "IMSYS Abuse" or "Informational-measuring systems Ltd.; IMSYS Abuse".
- Secondary sources identify the operator as also known as MOSNET, with a web presence at mosnet.ru.
- The inventory consists of two main blocks in the 84.23.0.0/16 and 217.70.0.0/16 ranges, with no IPv6 prefixes announced.

Reputation
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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
