residential isp brazil access

AS61672 is operated by Entelvias provedor de internet ltda.

What it's used for

  • The address space carries static residential and business internet access, evidenced by reverse DNS entries such as 131-108-101-0.static.entelvias.com.br and 177-11-101-0.static.entelvias.com.br.
  • The AS announces 2048 IPv4 addresses across 2 prefixes and 18 IPv6 prefixes, while maintaining 29 observed neighbours; this ratio indicates a local access network rather than a transit 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.
