AS23201: the Telecel S.A. network

AS23201 is an internet Autonomous System operated by Telecel S.A. (Paraguay). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS23201?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS23201 was assigned to Telecel S.A. by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS23201 currently announces 65 IPv4 block(s), totaling about 789.5 thousand addresses (789,504 in all), registered in Paraguay. Services from Telecel S.A. are reached through these addresses.

What it means to see AS23201 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS23201. That means the other end sits on the Telecel S.A. network (Paraguay). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
