AS61508: the SGS VALLEVISION SRL network

AS61508 is an internet Autonomous System operated by SGS VALLEVISION SRL (Argentina). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS61508?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS61508 was assigned to SGS VALLEVISION SRL by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS61508 currently announces 1 IPv4 block(s), totaling about 1 thousand addresses (1,024 in all), registered in Argentina. Services from SGS VALLEVISION SRL are reached through these addresses.

What it means to see AS61508 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS61508. That means the other end sits on the SGS VALLEVISION SRL network (Argentina). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
