AS30058: the FDCSERVERS network

AS30058 is an internet Autonomous System operated by FDCSERVERS (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 AS30058?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS30058 was assigned to FDCSERVERS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS30058 currently announces 371 IPv4 block(s), totaling about 368.6 thousand addresses (368,638 in all), registered in the United States. Services from FDCSERVERS are reached through these addresses.

What it means to see AS30058 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS30058. That means the other end sits on the FDCSERVERS network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
