> Right now, with the {{DNS}} class, we can look up IPs of provided interface names ({{eth0}},
{{vm1}}, etc.). However, it would be useful if the I/F -> IP lookup also took a look at
subinterfaces ({{eth0:1}}, etc.) and allowed binding to only a specified subinterface / virtual
> This should be fairly easy to add, by matching against all available interfaces' subinterfaces
via Java.
