Unclassified APNIC
Summary
Cdinet
isp residential regional brazil
AS61753 is operated by Maria Neusa Pereira de Sousa e Cia Ltda EPP, a regional internet service provider in Tocantins, Brazil.
What it's used for
- The address space carries residential and small business internet access, as indicated by the registrant's CNAE classification for "Serviços de comunicação multimídia" (multimedia communication services) and its operation as a Cable/DSL/ISP.
- The network announces 2048 IPv4 addresses across two /22 prefixes (131.100.16.0/22 and 168.181.232.0/22) and one IPv6 /32 prefix, with only 2 observed routing neighbours. This high address-to-neighbour ratio is characteristic of an access network providing last-mile connectivity rather than transit.
- Traffic from this AS consists of subscriber eyeballs and local business endpoints in the Itapiratins and Presidente Kennedy regions of Tocantins, Brazil.
Notable
- The registrants for both announced IPv4 prefixes (netnames 234559 and 275589) match the AS holder, confirming direct ownership of the address space.
- The operator is known locally as Cdinet, a name that appears in its web presence and application listings, distinguishing it from the formal legal entity name.
- The inventory consists of two contiguous /22 blocks in IPv4 and a single /32 in IPv6, representing a modest, self-contained estate typical of a regional ISP.

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 2026-10-21, 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 1,779 prefixes, as published 2026-10-22. 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.
