AS27756: the Servicio Satelital S.A. network

AS27756 is an internet Autonomous System operated by Servicio Satelital 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 AS27756?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS27756 was assigned to Servicio Satelital S.A. by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS27756 currently announces 2 IPv4 block(s), totaling about 3.8 thousand addresses (3,840 in all), registered in Argentina. Services from Servicio Satelital S.A. are reached through these addresses.

What it means to see AS27756 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS27756. That means the other end sits on the Servicio Satelital S.A. network (Argentina). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
