AS46003: the KOREACENTER-AS-KR CONNECTWAVE network

AS46003 is an internet Autonomous System operated by KOREACENTER-AS-KR CONNECTWAVE (South Korea). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS46003?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS46003 was assigned to KOREACENTER-AS-KR CONNECTWAVE by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS46003 currently announces 20 IPv4 block(s), totaling about 49.2 thousand addresses (49,152 in all), registered in South Korea. Services from KOREACENTER-AS-KR CONNECTWAVE are reached through these addresses.

What it means to see AS46003 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS46003. That means the other end sits on the KOREACENTER-AS-KR CONNECTWAVE network (South Korea). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
