IP swapping for network restart or reboot for ubuntu client

[Kraishak Mahtha]

Hi Wayne,

Thanks for sharing the link,

I have observed that I am seeing this IP switch only if it is in a
primary-failover mode whereas if we run the DHCP server standalone we do
not see any issue and the IP is being constant, by any chance did you try
this case
