AS28196: the BANCO VOTORANTIM SA network

AS28196 is an internet Autonomous System operated by BANCO VOTORANTIM SA (Brazil). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS28196?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS28196 was assigned to BANCO VOTORANTIM SA by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS28196 currently announces 1 IPv4 block(s), totaling 512 addresses (512 in all), registered in Brazil. Services from BANCO VOTORANTIM SA are reached through these addresses.

What it means to see AS28196 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS28196. That means the other end sits on the BANCO VOTORANTIM SA network (Brazil). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
