AS8820: the TAL-DE Tal.de GmbH network

AS8820 is an internet Autonomous System operated by TAL-DE Tal.de GmbH (Germany). Here is what that means and why this number may show up when you investigate a connection on your network.

What is AS8820?

An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS8820 was assigned to TAL-DE Tal.de GmbH by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.

Reach on the internet

AS8820 currently announces 27 IPv4 block(s), totaling about 42.5 thousand addresses (42,496 in all), registered in Germany. Services from TAL-DE Tal.de GmbH are reached through these addresses.

What it means to see AS8820 on your network

When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS8820. That means the other end sits on the TAL-DE Tal.de GmbH network (Germany). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
