There currently doesn’t seem to be any hooks in Zephyr for getting a
callback when a DNS server is added or removed which would be useful for on systems where setting up DNS takes longer than it takes to add a network interface, so there is the potential for a network interface to be added, a
callback to be sent to the user application and a TCP connection attempt before DNS is added – is there a way to get a notification when DNS has been added that I’ve overlooked?
