What it means to see AS23307 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS23307. That means the other end sits on the CDE-NS network (Canada). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
