We have a page for that !
This is really up to you: that's the magic of open protocols.
Many users run Bird or FRRouting in a VPS, but there is a variety of BGP implementations in use across the network and some networks even run hardware routers or experimental software. DN42 is a great place to try out and get familiar with your implementation of choice in a live network.
Sure. As long as you have a 24/7 connection, can configure VPN tunnels and run BGP then you can connect to DN42. Do let your peers know if you have a dynamic IP address and you may also want to consider preventing transit traffic through your network if you have a relatively slow connection.
Many users do use a virtual private server (VPS) for connecting to DN42. A VPS is a relatively cheap option that is always on and which (typically) provides a faster, more stable connection than your home. VPS have another advantage that if you mess something up, you won't break your home access to the internet.
The DN42 registry used to be maintained in monotone, but was moved to git following resource and performance issues. There may still be references back to monotone in some of the documentation, but the registry location is now:
AS number: Yes, see AS206633/AS205532 for example
IP: Probably no. Globally routable IPs are not supported in DN42; whilst in theory they could be announced, there are filters in place used by almost all networks which prevent that, and some networks will filter traffic to the private DN42 range only to enhance security. It's literally impossible to convince the whole of dn42 to lift those filters.
If you'd like to explore dn42 without too many changes to your network, you could announce both IPv6 GUA and ULA addresses to your network. IPv6 has a specified source address selection process which means that a host will always use an ULA address to talk to ULA destinations and a GUA address to talk to GUA destination.
DN42 supports IPv6 and some users do run IPv6 only networks. DN42 uses the "Unique Local Address" range (ULA, fd00::/8) defined by RFC 4193.
DN42 now uses ASNs in the 4242420000-4242429999 range, but the 76100-76199 range was used historically, and there are still a very small number of networks using legacy ASNs that have not migrated.
Previously, DN42 has used a two other ASN ranges:
We used to assign ASN in the 64600-64855 range, where you would get ASN 64600+X if you had 172.22.X.0/24. Once the address range was extended to include additional blocks, this process was obsoleted. Another issue with the private ASN range 64512-65534 was that other projects are also using it (for instance, Freifunk, Anonet, etc), which can lead to conflicts.
Yes, the wiki can be edited when browsing to wiki.dn42.
