I’m having trouble understanding why certain MAC addresses can’t be assigned to containers. AFAIK 4b:b0:5f:a1:23:c2 is a valid mac address. However, when I try assign it to either windows or Linux containers I get errors which I’ve never had a problem with before.
I was hoping someone could shed some light on why this might be happening?
Thanks in adv.
docker run --mac-address="4b:b0:5f:a1:23:c2" library/hello-world
