Description

The ip_address command is used to show and/or change the basic IP addresses used by RedBoot. IP addresses may be given as numeric values, e.g. 192.168.1.67, or as symbolic names such as www.ecoscentric.com if DNS support is enabled.

The -b option is used to cause the target to perform a bootp or dhcp negotiation to get an IP address.

The -l option is used to set the IP address used by the target device. The network mask length can also be specified

The -h option is used to set the default server address, such as is used by the load command.

The -d option is used to set the default DNS server address which is used for resolving symbolic network addresses. Note that an address of 0.0.0.0 will disable DNS lookups.
