Bug Description
I've several scripts which runs when my interface is brought up/down. Depending on the network my laptop is connected to, it starts/applys different settings. This scripts are located in /etc/network/
Recently we have implemented IPv6 in our company and I've noticed that the scripts topped to work.
Investigating, I've found that a IPv6 is configured automatically first and later eth0 receives IPv4 address, but this time the scripts are not called again.
So, the problem is when the script runs, we don't have IPv4 adress yet, and when we receive IPv4 address, the scripts are not called again.
And this is not an expected behaviour.
As a workarround, I've set to ignore "IPv6" in a network manager. But this problem may affect all the scripts located in /etc/network/
Step to reproduce the problem:
1. Get the mixed environment (IPv6/IPv4), with a DHCP for IPv4 and auto-configuration for IPv6. The IPv4 DHCP server is slower than IPv6 configuration.
2. Allow the Network manager to connect.
3. The scripts only will run once, when IPv6 address wil lbe received (Or I suppouse if IPv4 is faster, then only when IPv4 address is received, but not tested).
My Linuxmint version:
lsb_release -a

Also seeing this on Ubuntu 14.04. Mixed network, have an if-up.d script to restart minidlna - but sometimes it gets restarted after an IPv6 address has been obtained but before an IPv4 address is configured.
