AS23969: the TOT-NET TOT Public Company Limited network

AS23969 is an internet Autonomous System operated by TOT-NET TOT Public Company Limited (Thailand). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS23969?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS23969 was assigned to TOT-NET TOT Public Company Limited by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS23969 currently announces 189 IPv4 block(s), totaling about 1.2 million addresses (1,151,488 in all), registered in Thailand. Services from TOT-NET TOT Public Company Limited are reached through these addresses.

What it means to see AS23969 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS23969. That means the other end sits on the TOT-NET TOT Public Company Limited network (Thailand). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
