Summary
Net Jacarei
isp residential brazil broadband

What it's used for
- The address space carries residential broadband traffic, evidenced by reverse DNS entries such as

- Traffic from this AS consists of subscriber eyeballs for broadband internet services in the Jacareí region of São Paulo, Brazil.
Notable
- All registrants for the announced prefixes are listed as Netjacarei Telecon Ltda, matching the AS holder.
- The address inventory is composed of five distinct IPv4 blocks, including a /21 and four /22s, alongside a single /32 IPv6 prefix.

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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
