Summary

SINALNET

Brazil · AI-generated

isp residential regional brazil

SINALNET Comunicacoes is the AS handle for SINALNET, a regional cable and DSL internet service provider in Brazil.

What it's used for

  • The address space carries residential and small business subscriber traffic, evidenced by the reverse DNS record 131.72.102.254.static.sinal.net.br and the registrant netname 235091.
  • The network announces 1024 IPv4 addresses and 1 IPv6 prefix, with only 3 observed routing neighbours, indicating a small-scale access network rather than a transit provider.
  • Traffic from this AS consists of end-user internet access for SINALNET's regional subscriber base.

Notable

  • The RDAP registrant SINALNET Comunicações matches the AS holder name, confirming consistent ownership of the announced space.
  • The inventory consists of a single contiguous IPv4 block, 131.72.100.0/22, and one IPv6 prefix, 2804:1c48::/32, representing a compact and unified address 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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
