What is AS54218?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS54218 was assigned to BERENET by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS54218 currently announces 2 IPv4 block(s), totaling 512 addresses (512 in all), registered in the United States. Services from BERENET are reached through these addresses.
What it means to see AS54218 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS54218. That means the other end sits on the BERENET network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
