AS393876 is an internet Autonomous System operated by AS-PMGAA (the United States). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS393876?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS393876 was assigned to AS-PMGAA by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS393876 currently announces 1 IPv4 block(s), totaling 256 addresses (256 in all), registered in the United States. Services from AS-PMGAA are reached through these addresses.

What it means to see AS393876 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS393876. That means the other end sits on the AS-PMGAA network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.

How to see every connection and network your devices reach
