AS7690: the MIRAI Mirai Communication Network Inc. network

AS7690 is an internet Autonomous System operated by MIRAI Mirai Communication Network Inc. (Japan). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS7690?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS7690 was assigned to MIRAI Mirai Communication Network Inc. by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS7690 currently announces 9 IPv4 block(s), totaling about 38.9 thousand addresses (38,912 in all), registered in Japan. Services from MIRAI Mirai Communication Network Inc. are reached through these addresses.

What it means to see AS7690 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS7690. That means the other end sits on the MIRAI Mirai Communication Network Inc. network (Japan). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
