In the end I had to look in the BIND ARM.
As I read this, the solution should be:
options {
listen-on { ! 10.0.1.1; any;};
};
The first part tells bind to not listen to 10.0.1.1 and the second part
tells bind to listen on any other address.
Having the Listen-on statement removes the default listen for all addresses.
