In order to manage the 'only possible' ip address on an interface or set
of interfaces, the ip.sh script would have to handle a whole lot more
than it was designed:

- device activation
- module loading
- routing configuration

This would it very complex.  Right now, it is very simple: use existing
routes and devices.

Possible solutions:

* Edit the ip.sh script to do what you want directly.

* Use a custom script to start apache & bring up your IP address rather
than using ip.sh to do it.

* Statically assign a couple of IP addresses and mask them using noarp
option or arptables.
