Description

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 interface.

This should be fairly easy to add, by matching against all available interfaces' subinterfaces via Java.

Sub-Tasks

• [DNS] Log a WARN when there's no matching interface and we are gonna use the default one.: Resolved
