Ohh, Autoconfig (with the MAC-Address in the host bits) actually makes
it easier for me to log into a workstation.
I just keep 2 lists:
1) all prefixes in my network
2) all Macaddresses in use.
Now I can loop through all prefixes and try to ping the macaddress I want
to reach (with the occasional fffe in the middle).
Hoping that the MAC is really unique (we do not use 3com cards
anymore) I can actually find a specific Laptop on my network
easy without even knowing where the user is.

I agree to that, though.

Knowing what the host-part of the IP-Address will be for the a
specific device is an advantage I believe.
