Unclassified RIPE
Summary
OSS Ltd
business russia ipv4
OSS-LTD-AS is held by OSS Ltd.
What it's used for
- The address space is registered under the netname
OSS-LTD-NETfor all six announced IPv4 prefixes. - The AS announces 2048 IPv4 addresses across 6 prefixes with a single observed neighbour, indicating a small, self-contained network rather than a transit or large access provider.
- The inventory consists entirely of IPv4 space within the 178.217.72.0/23 to 178.217.77.0/24 range, with no IPv6 prefixes announced.
Notable
- All registrants for the announced prefixes are listed as
OSS Ltd, matching the AS holder. - The address inventory is finely subdivided into six contiguous blocks, suggesting internal segmentation for a corporate or business estate.

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: 453 networks and 1,846 prefixes, as published 2026-11-12. 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.
