PRIME FIBRA LTDA is the AS handle for Prime Fibra, a regional fiber-optic internet service provider in Brazil.
What it's used for
- The address space carries residential fiber subscribers, evidenced by reverse DNS records pointing to
proveminas.com.bracross all sampled addresses. - The network announces 5120 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, with only 3 observed routing neighbours, indicating a local access network rather than a transit provider.
- Traffic consists of end-user internet access for residential customers in the Minas Gerais region, consistent with the operator's business of providing fiber-optic connectivity.
Notable

PRIME FIBRA LTDAas the holder, matching the AS name and confirming consistent ownership of the announced space. - Prime Fibra emerged from the infrastructure of Proveminas (Empresa Mineira de Telecomunicações), representing a rebranding or evolution of the former telecom operator into a dedicated fiber ISP.
- The inventory is concentrated in the 189.76.0.0/16 range with a smaller block in 177.23.0.0/16, reflecting a consolidated regional footprint.

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.
