AS9531: the GEDU-AS-KR Gwangju Education Research Information Service network

AS9531 is an internet Autonomous System operated by GEDU-AS-KR Gwangju Education Research Information Service (South Korea). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS9531?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS9531 was assigned to GEDU-AS-KR Gwangju Education Research Information Service by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS9531 currently announces 3 IPv4 block(s), totaling about 36.1 thousand addresses (36,096 in all), registered in South Korea. Services from GEDU-AS-KR Gwangju Education Research Information Service are reached through these addresses.

What it means to see AS9531 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS9531. That means the other end sits on the GEDU-AS-KR Gwangju Education Research Information Service network (South Korea). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
