Great.

Looks good. :)

 MR> And all the trouble for just one single node which got an INO4 flag :)

Seems a lot of work, but it is good to be prepaired for the future and I do expect to see more INO4 flags in the nodelist in the foreseeable future. It may take a while, but the time that a sysop can only get a DS-Lite connection without extraordinary effort or cost is coming.

on the bright side, I think that with 50+ listed IPv6 nodes, we have enough "mass" to make it feasable to run a Fdionet node on a DS-Lite connection.  A DS-Lite node still can make outgoing IPv4 connections, so it can poll IPv4 only nodes to get mail. Mail destined for it can be routed via one of the 50+ IPv6 capable IPv6 nodes. It should be doable...


Cheers, Michiel
