What is AS33915?
An Autonomous System (ASN) is a block of networks under a single control with its own routing policy on the internet. The number AS33915 was assigned to TNF-AS by an RIR (regional internet registry). All traffic entering or leaving that network is announced under this number.
Reach on the internet
AS33915 currently announces 120 IPv4 block(s), totaling about 6.6 million addresses (6,588,928 in all), registered in the Netherlands. Services from TNF-AS are reached through these addresses.
What it means to see AS33915 on your network
When you investigate where a connection from your computer or phone comes from (or goes to), you may find AS33915. That means the other end sits on the TNF-AS network (the Netherlands). It can be legitimate — a cloud service, an ISP, a CDN — or an unexpected connection worth checking.
