AS6057: the Administracion Nacional de Telecomunicaciones network

AS6057 is an internet Autonomous System operated by Administracion Nacional de Telecomunicaciones (Uruguay). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS6057?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS6057 was assigned to Administracion Nacional de Telecomunicaciones by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS6057 currently announces 19 IPv4 block(s), totaling about 2.2 million addresses (2,155,520 in all), registered in Uruguay. Services from Administracion Nacional de Telecomunicaciones are reached through these addresses.

What it means to see AS6057 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS6057. That means the other end sits on the Administracion Nacional de Telecomunicaciones network (Uruguay). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
