What it means to see AS16906 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS16906. That means the other end sits on the El Salvador Network, S. A. network (SV). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
