Howto configure multiple MAC address with one ip-address (not at the same time) ???

[Sten Carlsen]

This is absolutely doable, I set this up long ago.

I actually have both interfaces configured to the same address at the
same time as standard.

This means that I can start a download using the wired connection , pull
out the cable and it will continue wireless.

host silver {
option dhcp-client-identifier "\000silver";
# hardware ethernet 00:03:93:eb:7f:59;
# hardware ethernet 00:03:93:d3:c3:36;
fixed-address silver.s-carlsen.dk.;
}

This works for me, both interfaces will get the same IP at the same
time. No bad effects have been observed yet after 4 years.
