AS9952: the HOSTWAY-AS-KR Hostway IDC network

AS9952 is an internet Autonomous System operated by HOSTWAY-AS-KR Hostway IDC (South Korea). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS9952?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS9952 was assigned to HOSTWAY-AS-KR Hostway IDC by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS9952 currently announces 34 IPv4 block(s), totaling about 47.6 thousand addresses (47,608 in all), registered in South Korea. Services from HOSTWAY-AS-KR Hostway IDC are reached through these addresses.

What it means to see AS9952 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS9952. That means the other end sits on the HOSTWAY-AS-KR Hostway IDC network (South Korea). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
