Summary
Hostlocation LTDA
hosting business brazil
AS28666 is operated by Hostlocation LTDA, a Brazilian hosting and connectivity provider.
What it's used for
- The address space carries hosting infrastructure, indicated by reverse DNS entries such as
host8-65.brs.com.brand189-1-165-127.brs.com.br. - The AS announces 2304 IPv4 addresses across 4 prefixes and 30 IPv6 prefixes, while maintaining 48 observed neighbours. This ratio of moderate address inventory against a high number of peering partners suggests a role focused on transit and interconnection rather than large-scale residential access.
Notable
- All registrants for the announced prefixes are listed as HOSTLOCATION LTDA, matching the AS holder name.
- The operator is also known as GrupoHost or HostFiber, according to peering databases.
- The IPv4 inventory consists of four distinct blocks, including a /22 and three smaller prefixes, all registered under the same netname 359297 or 552421.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
