Linux Force DHCP client (dhclient) to renew ip address

Linux renew ip command

The -r flag explicitly releases the current lease, and once the lease has been released, the client exits. For example, open terminal and type the command:

$ sudo dhclient -r

Now obtain fresh IP:

$ sudo dhclient

There is no need to restart network service. Above command should work with any Linux distro such as RHEL, Fedora, CentOS, Ubuntu and others. On a related note you can also try out the following commands:

# ifdown eth0

# ifup eth0

# /etc/init.d/network restart


# /etc/init.d/networking restart
