What is AS208180?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS208180 was assigned to CTS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

What it means to see AS208180 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS208180. That means the other end sits on the CTS network (the United Kingdom). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
