Summary
Nosis Laboratorio de Investigacion y Desarrollo S.A.
enterprise legacy
AS11392 is held by Nosis Laboratorio de Investigación y Desarrollo S.A., a Buenos Aires company founded in 1988 that sells commercial and financial information — credit and counterparty background data, compliance and fraud screening, foreign-trade records and marketing analytics — to Argentine businesses. The AS carries Nosis's own platform.
What it's used for
RIS sees four IPv4 /24s, 186.0.152.0/24 through 186.0.155.0/24 — 1,024 addresses — no IPv6, and two observed BGP neighbours. 186.0.0.0/8 is LACNIC space, consistent with an Argentine holder. Two upstreams and one contiguous kilo-block is a multi-homed enterprise, not a provider: a data company whose product is delivered as web portals and APIs needs its query endpoints reachable through more than one carrier, but has no reason to peer widely.
Notable
The reverse DNS names the workload directly. 186.0.154.133 resolves to ecommercenlb.nosis.com — a load balancer fronting the commercial platform, exactly the kind of host a subscription data service puts on the public edge.
Interesting
The other captured PTR, ppp-133.nosis.com.ar, is worth reading carefully rather than over-reading. ppp- names an access technology, a legacy point-to-point dial or leased-line naming convention, not a customer type, and one hostname is not evidence that Nosis operates as an ISP. It most likely survives from an older era when data vendors in Argentina delivered their feeds over dial-up sessions to subscriber terminals. The RDAP prefix lookups in the evidence pack failed, so registrant confirmation is absent — that is missing data, not a clearance, and the identification here rests on the rDNS and the holder record.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,783 prefixes, as published 2026-10-20. 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.
