About this network

AS28198 is operated by Sempre Telecomunicações Ltda, a Brazilian cable and DSL internet service provider.

What it's used for

• The address space carries residential and business customer traffic, evidenced by reverse DNS records consistently pointing to sempre.tec.br (e.g., 177-130-68-0.sempre.tec.br).
• The AS announces 68,352 IPv4 addresses across 50 prefixes and 60 IPv6 prefixes, while maintaining 171 observed routing neighbours. This high neighbour count relative to the address inventory indicates a role focused on peering and transit exchange rather than pure internal corporate segmentation.

Notable

• All sampled registrants for the largest prefixes are listed as SEMPRE TELECOMUNICACOES LTDA, matching the AS holder and confirming consistent ownership of the announced space.
• The inventory consists of a mix of /20, /21, and /22 IPv4 blocks, primarily in the 177.0.0.0/8, 186.0.0.0/8, and 187.0.0.0/8 ranges, alongside an IPv6 allocation under 2804:c90::/37.
