What it's used for
- The address space carries corporate infrastructure for a Brazilian credit, financing, and investment firm, as indicated by the registrant name and netname
184843. - The network announces a single IPv4 prefix,
186.233.143.0/24, comprising 256 addresses, with no IPv6 prefixes in inventory. - With only 2 observed neighbours, the low neighbour count relative to the address block suggests a small, self-contained corporate network rather than a transit or access provider.

- The RDAP registrant
NEGRESCO S/A - CREDITO, FINANCIAMENTO E INVESTIMENmatches the AS holder name exactly. - The inventory consists of a single contiguous /24 block, typical of a dedicated corporate allocation.

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 2026-11-03, 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: 448 networks and 1,851 prefixes, as published 2026-11-04. 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.
