What it means to see AS24477 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS24477. That means the other end sits on the NETAPPAS NetApp, Inc. network (Japan). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
