AS142622: the DIL-AS-AP Dream Information Laboratory network

AS142622 is an internet Autonomous System operated by DIL-AS-AP Dream Information Laboratory (Japan). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS142622?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS142622 was assigned to DIL-AS-AP Dream Information Laboratory by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS142622 currently announces 21 IPv4 block(s), totaling about 6.7 thousand addresses (6,656 in all), registered in Japan. Services from DIL-AS-AP Dream Information Laboratory are reached through these addresses.

What it means to see AS142622 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS142622. That means the other end sits on the DIL-AS-AP Dream Information Laboratory network (Japan). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
