Yay! It finally works!
DN42 IPv6 (AS4242422539): ✅
Clearnet IPv6 (AS201379): ✅
Legacy via NAT64/DNS64: ✅No Policy-Based Routing (PBR), just good old RFC 6724 (Default Address Selection for IPv6) working as intended to decide where a packet should go (DN42 or Clearnet).
No legacy IP addresses on the invididual Jails/VMs anymore, just clean inet6.
Internal addressing done manually, but routing information given by SLAAC/ND.
I like IPv6 🙂

New post: Joining DN42. The parallel hobbyist BGP network on WireGuard.
The setup: ASN registered via a git PR, MikroTik CHR on bhyve as border, three WireGuard peerings, FreeBSD jail running PowerDNS + nginx.
The fun part: blog.chofstede.dn42 serves the same content as blog.hofstede.it, but with a TLS cert signed by DN42's own CA and zero packets on the public internet. Two front doors to the same building.

Proper reverse-dns resolution also dialed in 🙂

I finally fixed my DN42 connection at home that broke with my last ISP switch 🙂
AS4242422539 is back online again 🙂
Is there someone, who's connected to DN42 and might try to ping me? (fdce:73f7:a2dc::1)

#DN42 searches for someone with hardware, expertise, time and passion to host, run and further develop their registry. It's a project of enthusiasts to play around with BGP in a lab and playground environment. There are plenty of hobbyists who run their own #ASN within this #darknet.
Announcement is here. More info on the project on one of their mirrors

I have developed mping-sender over the last few days. It is a simple program that sends a UDP packet to a (freely selectable) multicast address every second. It is therefore well suited for testing multicast. It is partially compatible with the mping client.
Furthermore, it is protected by landlock, seccomp, libcap-ng, AppArmor, and systemd.
