Endpoint address dns resolution - option to prefer IPv6 or IPv4

[Torsten Krah]

Hi,

I've got an endpoint with a DNS name which has both, an A and AAAA
record.
I would like to configure the client, so that I can tell him, to either
prefer IPv6 or IPv4 for the vpn connection.

How can I do that (no I don't want to remove either an A or AAAA record
from DNS - just in the client)?

If its not yet possible -  can support be added for this? I am also
happy with some code pointers where this decision is done to come up
with a patch maybe?

kind regards

Torsten
