You also need to contact other users and peer with them, so you can enter the 'real' DN42 step by step.ĭN42 is running on 172.20.0.0/14 and fd00::/8, IP blocks reserved for internal usage. Just like the real Internet, you will be playing the role of a ISP, register your personal ID, ASN, IPv4 and IPv6 blocks, and announce your IP blocks on your server with BGP. IS suitable for users with a real AS, but is worried of knocking out the Internet due to configuration errors, and want a test field.īecause of this, the bar to enter DN42 is a bit high.IS suitable for users learning about networking, practicing configuration of servers and routers, and even preparing for an AS on the real Internet.NOT suitable for users consuming large amounts of bandwidth/data, such as for unlocking streaming services.NOT suitable for users only seeking privacy protection or bypassing censorship.It uses much of the technology running on modern Internet backbones (BGP, recursive DNS, etc), and is a great replica of a real network environment. On the contrary, the goal of DN42 is to simulate another Internet. But unlike other traditional VPNs, DN42 itself doesn't provide any VPN exits, which means it doesn't allow you to bypass Internet censorships or unlock streaming services.

DN42, aka Decentralized Network 42, is a large, decentralized VPN-based network.
