AS10834: the Telefonica de Argentina network

AS10834 is an internet Autonomous System operated by Telefonica de Argentina (Argentina). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS10834?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS10834 was assigned to Telefonica de Argentina by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS10834 currently announces 73 IPv4 block(s), totaling about 369.4 thousand addresses (369,408 in all), registered in Argentina. Services from Telefonica de Argentina are reached through these addresses.

What it means to see AS10834 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS10834. That means the other end sits on the Telefonica de Argentina network (Argentina). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
