What is AS9319?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS9319 was assigned to HCNCHUNGJU-AS-KR HCN CHUNGBUK CABLE TV SYSTEMS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

What it means to see AS9319 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS9319. That means the other end sits on the HCNCHUNGJU-AS-KR HCN CHUNGBUK CABLE TV SYSTEMS network (South Korea). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
