This is my setup:

```
$ ip addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
    inet 10.0.2.0/24 scope global lo
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever

```

'lo' is magical in the sense that that 10.0.2.0/24 line actually creates ~250 bindable addresses. Most daemons bind to these without trouble. However, this does not work in my BIND9-config:

```
listen-on port 53 { 10.0.2.15; };

```

(I've tried without "port 53" too). The problem is that for BIND, listen-on is like a "binding whitelist", that it matches to all IPs it can find on all interfaces. In this case, it does not find 10.0.2.15 on any interfaces, so it does not bind.

Can anyone recommend a workaround? I should point out that this is a testing setup on which I am moving things around all the time so I would prefer a solution that does not involve too many moving parts.
