isp residential brazil fixed-line

AS53120 is operated by Mundivox Telecomunicações LTDA.

What it's used for

  • The address space carries fixed-line subscriber traffic, evidenced by reverse DNS entries such as mvx-187-111-23-255.mundivox.com and mvx-141-193-151-64.mundivox.com.
  • The network announces 4,352 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a local access provider rather than a transit carrier.
  • Traffic consists of residential and small business fixed-line internet users in Brazil, consistent with the operator's role as a regional telecommunications company.

Notable

  • Registrants for both announced prefixes (187.111.16.0/20 and 141.193.151.0/24) match the AS holder, Mundivox Telecomunicações LTDA.
  • The inventory is compact, comprising two distinct IPv4 blocks and a single /32 IPv6 prefix, typical of a regional ISP managing its own customer base.

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 1,778 prefixes, as published 2026-10-20. 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.
