Hello Markus,

On Monday April 25 2016 11:20, you wrote to Kees van Eeten:

So run the script on a daily basis with the DAILYLST.

It is not "we" - the Fidonet IPv6 community - that has to deal with this. It is the job of the nodelist clercks to keep tho nodelist accurate and up to date.

But... to get back on topic, you could add another switch; one that looks for the INO4 flag in the nodelist and excludes those nodes. So that IPv4 only nodes do not attempt to call an IPv6 only node.

Or for the more distant future: check against the list of IPv6 nodes, and exclude all others.

OTOH, by the time we have nodes that can not make outgoing calls om IPv4, the list of IPv6 nodes is too big to be maintained in its present form, IPv6 capability will be the default and we will have an INO6 flag to signal the exceptions in the nodelist...


Cheers, Michiel
