What it means to see AS263347 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS263347. That means the other end sits on the CEDNET PROVEDOR INTERNET network (Brazil). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
