What is AS23018?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS23018 was assigned to CSMGUSA by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS23018 currently announces 2 IPv4 block(s), totaling 768 addresses (768 in all), registered in the United States. Services from CSMGUSA are reached through these addresses.
What it means to see AS23018 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS23018. That means the other end sits on the CSMGUSA 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
