business it consulting brazil

AS61619 is held by Positivo S+ Solucoes em TI S.A.

What it's used for

  • The address space carries static infrastructure for Algar Tecnologia, as evidenced by reverse DNS records pointing to static.algartecnologia.com.br.
  • The AS announces 2,304 IPv4 addresses across 2 prefixes, with 2 observed routing neighbours, indicating a small-scale internal or corporate network rather than a large access or transit provider.
  • Traffic from this AS consists of IT consulting and technology solutions infrastructure, supporting business operations for the holder.

Notable

  • Registrants for both announced prefixes (186.237.200.0/21 and 138.36.246.0/24) are listed as POSITIVO S+ SOLUCOES EM TI S.A, matching the AS holder.
  • Positivo Tecnologia acquired Algar TI Consultoria SA, which explains the alignment between the AS handle ALGAR TI CONSULTORIA SA and the current registrant name.
  • The inventory consists of two distinct IPv4 blocks with no IPv6 prefixes, reflecting a focused corporate estate.

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.
