+## What's dn42
+
+![dn42 logo](dn42.png)
+
+[dn42](https://dn42.cc/) is a large, dynamic VPN that employs Internet technologies (BGP, whois database, DNS, etc.).  
+Participants connect to each other using network tunnels (GRE, OpenVPN, WireGuard, Tinc, IPsec) and exchange routes using the Border Gateway Protocol.
+
+### Why dn42?
+
+dn42 can be used to learn networking and to connect private networks, such as hackerspaces or community networks. But above all, experimenting with routing in dn42 is fun!
+
+## AS4242423884
+
+`AS4242423884`, aka NOETTORE-NETWORK, is my experimental network participating in the dn42 overlay network.  
+My assigned IPv4 prefix is `172.21.68.0/27` and the IPv6 prefix is `fded:aab3:fb63::/48`.
+
+### Nodes information

+Please sign the email with the PGP/SSH key as reported in your `-MNT` object in the [dn42 registry](https://git.dn42.dev/dn42/registry).
+
+- The node you want to peer with
+- Your node location
+- dn42 ASN
+- Wireguard endpoint and port (if available)
+- Wireguard public key
+- dn42 IPv4 (Not required if you choose to use Extended Next Hop)
+- dn42 IPv6
+- Tunnel link-local IPv6 address
