What it means to see AS265380 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS265380. That means the other end sits on the WSU Tecnologia Ltda network (Brazil). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
