What is AS12816?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS12816 was assigned to MWN-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS12816 currently announces 7 IPv4 block(s), totaling about 395 thousand addresses (395,008 in all), registered in Germany. Services from MWN-AS are reached through these addresses.
What it means to see AS12816 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS12816. That means the other end sits on the MWN-AS network (Germany). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
