AS10430: the WA-K20 network

AS10430 is an internet Autonomous System operated by WA-K20 (the United States). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS10430?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS10430 was assigned to WA-K20 by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS10430 currently announces 45 IPv4 block(s), totaling about 539.1 thousand addresses (539,136 in all), registered in the United States. Services from WA-K20 are reached through these addresses.

What it means to see AS10430 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS10430. That means the other end sits on the WA-K20 network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
