AS55610: the MSAFER-AS-KR KAIT network

AS55610 is an internet Autonomous System operated by MSAFER-AS-KR KAIT (South Korea). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS55610?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS55610 was assigned to MSAFER-AS-KR KAIT by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS55610 currently announces 3 IPv4 block(s), totaling about 1 thousand addresses (1,024 in all), registered in South Korea. Services from MSAFER-AS-KR KAIT are reached through these addresses.

What it means to see AS55610 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS55610. That means the other end sits on the MSAFER-AS-KR KAIT network (South Korea). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
