What is AS203351?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS203351 was assigned to UBER-EMEA by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS203351 currently announces 1 IPv4 block(s), totaling 256 addresses (256 in all), registered in the Netherlands. Services from UBER-EMEA are reached through these addresses.
What it means to see AS203351 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS203351. That means the other end sits on the UBER-EMEA network (the Netherlands). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
