What it means to see AS60273 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS60273. That means the other end sits on the ALTANETICA Altanetica S.L. network (Spain). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
