What it means to see AS205951 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS205951. That means the other end sits on the MCBBANKDXB network (the United Arab Emirates). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
