Summary

Avato

Brazil · AI-generated

residential isp brazil access

The AS handle AVATO TECNOLOGIA S.A is held by Avato, a Brazilian telecommunications provider.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS records pointing to avato.com.br and avato.br.
  • The network announces 16,384 IPv4 addresses across 6 prefixes and 58 IPv6 prefixes, while maintaining only 1 observed neighbour, a ratio characteristic of an access or eyeball network rather than a transit provider.

Notable

  • Registrants for the largest prefixes are listed as BRASIL TECPAR | AMIGO | AVATO, indicating a consolidation of address space from predecessor entities.
  • The inventory consists of contiguous IPv4 blocks in the 201.71.128.0/18 range and a large IPv6 allocation under 2804:1408::/34.

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 2026-11-03. 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.
