Hello,

thanks for your help.

All right, now I see. It's a "nice to have feature", but I don't rely on
it. If it disturbs, than I will find a solution.

The second point might only be relevant to me in this case with a bad
ISP. I am using SLAAC and can't change the MAC address, due to a driver
bug. And that's only if you haven't fixed IP addresses or such strange
kind of dynamically created address space.

Ahh, that's good to know, than it also ignores the Shared Address Space
for use in ISP CGN: 100.64.0.0/10. As I remember it was recognized, but
I've used FQDNs with the Address option. Does autodetection take really
longer, than to configure a static IP address?

Reiner
