Ubuntu releases its IP during system reboot/shutdown

[Sourav Maity]

Hi,

I got a weird problem in our setup. Every time I reboot Ubuntu systems it is releasing its IP from the DHCP server. So the IP is getting free in DHCP. Therefore in some cases DHCP is offering the same IP to other system. And its then difficult to find the new IP assigned to the system as it is located at remote location. IP reservation may help, but we cannot go for reservation as we have huge number of system.

I checked with other distributions(RHEL/CentOS/Fedora/Windows), those systems does not release IP during system reboot/shutdown

And the IP release is happening when the interface is added in /etc/network/interfaces file with dhcp options.

Kindly suggest how can I prevent IP release during system shutdown/reboot in Ubuntu
