debian change from dhcp to static IP

One would think to achieve the update from the DHCP assigned IP to the static one, the only thing to do is to update your /etc/network/interfaces

from:

iface eth0 inet dhcp

to:

iface eth0 inet static
        address 10.165.248.252
        netmask 255.255.248.0
        gateway 10.165.248.1
        broadcast 10.165.248.255
        network 10.165.248.0

and restart:

/etc/init.d/networking restart

(optionally you can adjust your /etc/resolv.conf (to update DNS servers, and search paths)

The changed IP is immediately visible.

How surprised I was when after couple of hours the IP was changed back to the one from the DHCP pool. (resolv.conf was then automatically updated from the DHCP server)

Solution was to kill the dhcp3-client. (and change again the resolv.conf and restart networking)
