What is AS538?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS538 was assigned to DNIC-AS-00538 by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS538 currently announces 2 IPv4 block(s), totaling 512 addresses (512 in all), registered in the United States. Services from DNIC-AS-00538 are reached through these addresses.
What it means to see AS538 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS538. That means the other end sits on the DNIC-AS-00538 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
