Assuming this the broken state you're describing (as you've attached before and after log copies), from the log messages above it seems the interface is not available when named is being started. I have seen this behavior with several other services on Fedora that need manual restart after boot (e.g., postfix, nginx and sshd) to make them listen on all configured interfaces because the interface was not configured when the service was being started.
