Assigning an IP address manually
If you do not want J-Link to be configured via DHCP, you can assign an IP address
and a subnet mask (optional) manually. This is done via the ipaddr command in
JLink.exe. This command can be used in four different ways, which are explained in
the table below:
Command
ipaddr
ipaddr <IP>
ipaddr <IP> <Subnet mask>
ipaddr DHCP
Table 3.1: ipaddr command description
Example ipaddr
J-Link>ipaddr
DHCP assigned network configuration
IP-Addr: 192.168.199.29
Subnetmask: 255.255.0.0
Example ipaddr <IP>
J-Link>ipaddr 192.168.87.115
IP address successfully changed to '192.168.87.115'.
Subnetmask successfully changed to '255.255.0.0'.
Example ipaddr <IP> <Subnet mask>
J-Link>ipaddr 192.168.87.116 255.255.0.0
IP address successfully changed to '192.168.87.116'.
Subnetmask successfully changed to '255.255.0.0'.
Example ipaddr DHCP
J-Link>ipaddr DHCP
Configuration successfully changed to DHCP.

CHAPTER 3
If no additional parameter is specified, the current
IP and subnet mask of J-Link are shown.
If an IP is given as an additional parameter the
given IP address is set as the IP address for J-Link.
A default 16-bit subnet mask (255.255.0.0) is used.
From this time J-Link uses this static IP, DHCP is
disabled from this point.
If an IP and a subnet mask is given as an additional
parameter, the given IP and the given subnet mask
are used. From this time J-Link uses this static IP
and subnet mask, DHCP is disabled from this point.
If DHCP is given as an additional parameter the use
of DHCP is enabled the next time J-Link boots up.
This especially makes sense if a static IP address
was previously used and now an IP address given
by the DHCP Server shall be used.
