There is an important difference between the data model of monotone and GIT: In GIT branches are HEADs, while in monotone, branches are a list of HEADs. Or, to state it simpler and probably less correct: It is possible to sync merge conflicts in monotone. In GIT, conflicts are part of the index and/or working tree, and thus can't be pushed/pulled.
The DN42 registry is stored on multiple monotone servers which sync with each other. This is not possible in GIT, because the GIT servers don't know how to handle merge conflicts. In monotone, the servers just sync the conflict.
There are some ASes in dn42 that route IPv6 traffic. It is not yet agreed upon what prefixes should be used. The following proposals are the more sane ones:
At the moment, it is safe to assume that everyone doing IPv6 routing accepts at least prefixes from fd00::/8 with prefix lengths between 48 and 64 bits (inclusive) if they are part of the registry.
Yes, we know that this is not private ASN space (rather, it is part of the reserved block 65552-131071, see IANA).
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. Since we are now assigning /25 by default, and we have extended the address range to include 172.23.0.0/16, this is legacy.
Another issue with the private ASN range 64512-65534: other projects are also using it (for instance, Freifunk, Anonet, etc), which can lead to conflicts.
Fortunately, RFC6996 defines a new private ASN range: 4200000000-4294967294. Given the size of this range, there is little chance of running into a conflict.
We now encourage dn42 users to use the newly-allocated ranges in 4242420000-4242429999. See the registry page for details.
This is really up to you: that's the magic of open protocols.
As of 2014, most people seem to use either Quagga or Bird (with a growing preference for Bird). You may also encounter users of OpenBGPd. Even more occasionally, people use hardware BGP routers in dn42, for instance Extreme Networks hardware.
Yes, but only when connecting to this site via dn42 over SSL.
