dhcp

dhcp

Synopsis
dhcp <device> configures a network interface using DHCP
Details
The dhcp command configures the network interface given by <device> using settings obtained using DHCP. DHCP is the most commonly used network configuration protocol. The protocol provides an IP address and netmask for the machine, and the IP addresses of the local gateway and the local DNS service.

DHCP allocates IP address dynamically. A DHCP server will often allocate the same IP address to a given machine, but this is not guaranteed. If you require a fixed IP address for your JNode machine, you should use bootp or ifconfig. (And, if you have a DHCP service on your network, you need to configure it to not reallocate your machine's staticly assigned IP address.)
