Summary
Brisanet
residential fiber isp brazil
The AS handle BRISANET SERVICOS DE TELECOMUNICACOES S.A is held by Brisanet.
What it's used for
- The address space carries residential and fixed broadband traffic, evidenced by reverse DNS entries such as
tmp.dynamic.brisanet.net.brand187-19-207-255-tmp.static.brisanet.net.br. - The AS announces 83,968 IPv4 addresses and 30 IPv6 prefixes, maintaining 214 observed neighbours; this high neighbour count relative to the address inventory indicates a transit and peering-heavy role for a major regional ISP.
Notable
- Registrants are consistent with the announcer, primarily
BRISANET SERVICOS DE TELECOMUNICACOES S.A, with some older prefixes registered toBrisanet Prestacao De Servicos De Internet Ltda. - The address inventory is finely subdivided across multiple /19, /20, and /21 blocks in the 177.37, 187.19, and 206.42 ranges, reflecting a large-scale internal corporate estate for site-by-site segmentation.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 431 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.
