Vous pouvez aussi use this command:
dhclient -r interface
dhclient interface
Where interface is le device you want to get a nouveau address for. Par exemple,
dhclient -r eth0
dhclient eth0
The -r flag forces dhclient to premier release tout leases you have. The second command requests a nouveau lease.
From man dhclient:
-r Tell dhclient to release the current lease it has from the
server. This is not required by the DHCP protocol, but some
ISPs require their clients to notify the server if they wish
to release an assigned IP address.
