AS23974: the MOE-AS-AP Ministry of education network

AS23974 is an internet Autonomous System operated by MOE-AS-AP Ministry of education (Thailand). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS23974?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS23974 was assigned to MOE-AS-AP Ministry of education by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS23974 currently announces 21 IPv4 block(s), totaling about 114.2 thousand addresses (114,176 in all), registered in Thailand. Services from MOE-AS-AP Ministry of education are reached through these addresses.

What it means to see AS23974 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS23974. That means the other end sits on the MOE-AS-AP Ministry of education network (Thailand). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
