AS15208: the Servicio de Impuestos Internos network

AS15208 is an internet Autonomous System operated by Servicio de Impuestos Internos (Chile). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS15208?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS15208 was assigned to Servicio de Impuestos Internos by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS15208 currently announces 1 IPv4 block(s), totaling 768 addresses (768 in all), registered in Chile. Services from Servicio de Impuestos Internos are reached through these addresses.

What it means to see AS15208 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS15208. That means the other end sits on the Servicio de Impuestos Internos network (Chile). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
