What is AS13485?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS13485 was assigned to GCU by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS13485 currently announces 6 IPv4 block(s), totaling about 53.2 thousand addresses (53,248 in all), registered in the United States. Services from GCU are reached through these addresses.
What it means to see AS13485 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS13485. That means the other end sits on the GCU network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
