AS7049: the Silica Networks Argentina S.A. network

AS7049 is an internet Autonomous System operated by Silica Networks Argentina S.A. (Argentina). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS7049?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS7049 was assigned to Silica Networks Argentina S.A. by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS7049 currently announces 24 IPv4 block(s), totaling about 24.3 thousand addresses (24,320 in all), registered in Argentina. Services from Silica Networks Argentina S.A. are reached through these addresses.

What it means to see AS7049 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS7049. That means the other end sits on the Silica Networks Argentina S.A. network (Argentina). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
