About this network

AS53167 is operated by Sebratel Tecnologia Ltda.

What it's used for

• The address space carries residential subscriber traffic, evidenced by reverse DNS entries such as static.sebratel.psi.br and p-cgn-.sebratel.psi.br, indicating static IP assignments and carrier-grade NAT gateways.
• The AS announces 7424 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, while maintaining 12 observed neighbours; this ratio of address volume to peering partners is characteristic of an access network serving end-users rather than a transit provider.
• Traffic originates from cable and DSL subscribers in Brazil, consistent with the operator's business model as a regional ISP providing broadband connectivity.

Notable

• Registrants for the three largest prefixes (186.219.128.0/20, 177.22.176.0/21, 143.202.132.0/22) are all listed as SEBRATEL TECNOLOGIA LTDA, aligning with the AS holder.
• The smallest announced prefix, 209.61.9.0/24, is registered to Cogent Communications, LLC with netname COGENT-209-61-16, suggesting leased or historically allocated space distinct from the primary Sebratel inventory.
• The inventory consists of four distinct IPv4 blocks of varying sizes, ranging from a /20 to a /24, alongside a single /32 IPv6 prefix.
