Summary

Precisa Internet e Comunicação

Brazil · AI-generated

residential isp brazil scm

AS61732 is operated by Precisa Internet e Comunicação Ltda.

What it's used for

  • The address space carries dynamic subscriber traffic, as evidenced by reverse DNS entries such as 131-72.105-0.dynamic.hoby.com.br and 170-247.17-0.dynamic.hoby.com.br.
  • The AS announces 2048 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 10 observed neighbours, indicating a local access network rather than a transit provider.
  • Traffic consists of residential broadband subscribers in Sidrolândia, Mato Grosso do Sul, served under a Multimídia Communication Services (SCM) license.

Notable

  • Registrants for both announced prefixes (131.72.104.0/22 and 170.247.16.0/22) match the AS holder, Precisa Internet e Comunicação Ltda.
  • The inventory consists of two /22 IPv4 blocks and a single /32 IPv6 prefix, typical of a regional ISP managing its own allocated space.

Reputation

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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
