AS7622: the ASN-KAIST-SAL Korea Advanced Institute of Science and Technology network

AS7622 is an internet Autonomous System operated by ASN-KAIST-SAL Korea Advanced Institute of Science and Technology (South Korea). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS7622?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS7622 was assigned to ASN-KAIST-SAL Korea Advanced Institute of Science and Technology by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS7622 currently announces 1 IPv4 block(s), totaling about 16.4 thousand addresses (16,384 in all), registered in South Korea. Services from ASN-KAIST-SAL Korea Advanced Institute of Science and Technology are reached through these addresses.

What it means to see AS7622 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS7622. That means the other end sits on the ASN-KAIST-SAL Korea Advanced Institute of Science and Technology network (South Korea). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
