What is AS56508?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS56508 was assigned to ARDC by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS56508 currently announces 6 IPv4 block(s), totaling about 65.3 thousand addresses (65,280 in all), registered in the United States. Services from ARDC are reached through these addresses.
What it means to see AS56508 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS56508. That means the other end sits on the ARDC network (the United States). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
