Summary
Sisalweb Internet
isp residential fiber regional
SISALWEB INTERNET is the AS handle for Sisalweb Internet, a regional internet service provider based in Bahia, Brazil.
What it's used for
- The address space carries residential and small business subscriber traffic, evidenced by reverse DNS entries pointing to
sisalweb.net.brand the operator's provision of fiber optic, cable, and radio link services. - The network announces 3072 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, while maintaining 23 observed neighbours; this ratio of modest address inventory against a moderate peer count indicates an access network rather than a transit provider.
- Traffic from this AS consists of end-user internet access for individuals and local businesses in the Conceição do Coité region, utilizing the operator's fiber and cable infrastructure.
Notable
- All registrants for the announced prefixes (
131.221.72.0/22,143.202.176.0/22,177.86.24.0/22) are listed as SISALWEB INTERNET, matching the AS holder. - The address inventory is composed of three distinct /22 blocks, each with a unique netname (
240371,266234,198501), reflecting a segmented corporate estate for different service tiers or acquisition phases.

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.
