Summary

NexNet Fibra Internet

Brazil · AI-generated

isp residential fiber brazil

NEXNET FIBRA INTERNET is held by NexNet Fibra Internet.

What it's used for

  • The space carries residential and business fiber internet traffic, evidenced by reverse DNS entries like 177-86-58-0-nexnetfibra.com.br and the netname 198503.
  • The AS announces 2048 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with 6 observed neighbours, indicating a local access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for homes and small businesses in Brazil, as NexNet provides 100% fiber optic connectivity solutions.

Notable

  • The registrant THADEU REZENDE MUNIZ for the prefix 177.86.56.0/21 differs from the AS holder name, which may reflect individual ownership or a specific account holder within the organization.
  • The address inventory consists of a single /21 block and a /32 IPv6 prefix, typical for a regional ISP managing a specific geographic footprint.

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 2026-10-22. 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.
