AS23679: the NUSANET-AS-ID PT. Media Antar Nusa network

AS23679 is an internet Autonomous System operated by NUSANET-AS-ID PT. Media Antar Nusa (Indonesia). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS23679?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS23679 was assigned to NUSANET-AS-ID PT. Media Antar Nusa by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS23679 currently announces 35 IPv4 block(s), totaling about 23.6 thousand addresses (23,552 in all), registered in Indonesia. Services from NUSANET-AS-ID PT. Media Antar Nusa are reached through these addresses.

What it means to see AS23679 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS23679. That means the other end sits on the NUSANET-AS-ID PT. Media Antar Nusa network (Indonesia). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
