Registering a DN42 domain and setting up primary and secondary Knot DNS servers, including forward zones, IPv4/IPv6 reverse zones, and Registry entries.

Connecting DN42 nodes with WireGuard and dual-stack OSPFv3, then exchanging external routes over full-mesh iBGP, with notes on link-local addressing and BIRD configuration.

Joining DN42 by registering an ASN and address space, configuring BIRD, ROA checks, and WireGuard, and establishing BGP sessions with other members.
