AS59093 is an internet Autonomous System operated by ICKNET IMABARI CATV CORPORATION (Japan). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS59093?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS59093 was assigned to ICKNET IMABARI CATV CORPORATION by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

AS59093 currently announces 2 IPv4 block(s), totaling about 3.1 thousand addresses (3,072 in all), registered in Japan. Services from ICKNET IMABARI CATV CORPORATION are reached through these addresses.

What it means to see AS59093 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS59093. That means the other end sits on the ICKNET IMABARI CATV CORPORATION network (Japan). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
