AS48152: the DIGITAL-REALTY- network

AS48152 is an internet Autonomous System operated by DIGITAL-REALTY- (Germany). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS48152?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS48152 was assigned to DIGITAL-REALTY- by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS48152 currently announces 17 IPv4 block(s), totaling about 25.3 thousand addresses (25,344 in all), registered in Germany. Services from DIGITAL-REALTY- are reached through these addresses.

What it means to see AS48152 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS48152. That means the other end sits on the DIGITAL-REALTY- network (Germany). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
