Summary
Alt Informatica
isp regional brazil
AS52612 is operated by Alt Informatica Ltda.
What it's used for
- The address space carries subscriber traffic, evidenced by reverse DNS entries like
177-124-21-0.altinformatica.com.brand netnames200346and544884registered to Alt Informatica Ltda. - The AS announces 1536 IPv4 addresses across 2 prefixes and 3 IPv6 prefixes, with 7 observed neighbours; this ratio of address space to peering partners indicates a regional access network rather than a transit provider.
- As a regional ISP, the traffic consists of residential and small business subscriber eyeballs in the state of Minas Gerais, Brazil.
Notable
- Registrants for both announced IPv4 prefixes match the AS holder, Alt Informatica Ltda.
- The operator is also known as R2Net, a regional network service provider in Brazil.
- The inventory consists of two contiguous IPv4 blocks and three IPv6 prefixes, all located in Brazil.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
5 upstream, 3 downstream and 14 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, 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 2026-10-17. 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.
