isp residential brazil wireless

WI-MAX INTERNET LTDA is the AS handle for Wi-Max Internet.

What it's used for

  • The address space carries residential wireless access traffic, evidenced by the reverse DNS record 254-181-221-177.mapminas.com.br which points to a customer-facing domain.
  • The network announces 2048 IPv4 addresses across 1 prefix (177.221.176.0/21) and maintains 2 observed neighbours, a ratio consistent with a local access provider rather than a transit carrier.
  • Traffic from this AS consists of subscriber eyeballs accessing the internet via Wi-Max technology in the Minas Gerais region of Brazil.

Notable

  • The RDAP registrant WI-MAX INTERNET LTDA matches the AS holder name exactly.
  • The inventory consists of a single contiguous /21 block, indicating a straightforward address allocation without complex subdivision.

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 1,779 prefixes, as published 2026-10-21. 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.
