AS20965: the GEANT The GEANT IP Service network

AS20965 is an internet Autonomous System operated by GEANT The GEANT IP Service (the Netherlands). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS20965?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS20965 was assigned to GEANT The GEANT IP Service by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS20965 currently announces 2 IPv4 block(s), totaling about 9.2 thousand addresses (9,216 in all), registered in the Netherlands. Services from GEANT The GEANT IP Service are reached through these addresses.

What it means to see AS20965 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS20965. That means the other end sits on the GEANT The GEANT IP Service network (the Netherlands). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
