AS263213: the VISION NET network

AS263213 is an internet Autonomous System operated by VISION NET (Argentina). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS263213?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS263213 was assigned to VISION NET by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS263213 currently announces 5 IPv4 block(s), totaling about 1.5 thousand addresses (1,536 in all), registered in Argentina. Services from VISION NET are reached through these addresses.

What it means to see AS263213 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS263213. That means the other end sits on the VISION NET network (Argentina). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
