isp residential brazil local

BALSAS NET LTDA - ME is operated by Balsas Net LTDA - ME.

What it's used for

  • The address space carries local subscriber traffic, evidenced by reverse DNS entries such as 131-100-217-0.balsasnet.net.br and 131-100-218-254.balsasnet.net.br.
  • The network announces 1024 IPv4 addresses and 1 IPv6 prefix, with 3 observed neighbours, indicating a small-scale access provider rather than a transit carrier.
  • Traffic from this AS consists of residential and local business internet access for customers in the Balsas, Maranhão region.

Notable

  • The registrant BALSAS NET LTDA - ME matches the AS handle and the netname 235385 for the announced prefix 131.100.216.0/22.
  • The address inventory is compact, consisting of a single /22 IPv4 block and a /32 IPv6 prefix, typical of a regional internet service provider.

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.
