dn42 is a decentralised network designed to help people learn internet technologies such as BGP. It works in a similar way to the real internet, with people registering for ASNs and IPv4/6 address space, setting up their own BGP daemon, and peering with other dn42 users. dn42 uses 172.20.0.0/14 for its IPv4 space and fd00::/8 for IPv6.

My dn42 ASN is AS4242422253. I have 172.23.7.192/26 for IPv4 and fd36:dee8:4ab5::/48 for IPv6. I used to have nodes around the world, with them all connected internally using iBGP, ensuring that packets get routed to the correct server no matter which node they hit. Currently, I only have one public peering node which provides dn42 connectivity to my home via a WireGuard tunnel, though I likely will expand my network in the future.
