Can't get ConnectCore SBC IP address

This quesintion is releated to the ConnectCore 6 SBC, I’m trying to find the ip addresss of the board so that I get download and debug to the board.

I’m following the doc at
https://www.digi.com/resources/documentation/digidocs/90002284/#task/eclipse_ide/new/3_launch_the_application_in.htm%3FTocPath%3DDigi%2520Embedded%2520Yocto|Application%2520development|Develop%2520using%2520command%2520line|_____3

it says I should get a message like this after a ifconfig

eth0 Link encap:Ethernet HWaddr 00:11:22:33:22:11
inet addr:192.168.42.30 Bcast:192.168.42.255 Mask:255.255.255.0

collisions:0 txqueuelen:1000
RX bytes:119890110 (114.3 MiB) TX bytes:16714042 (15.9 MiB)

but in my board, I only got

eth0 Link encap:Ethernet HWaddr 00:04:F3:12:12:D6
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:4 errors:0 dropped:0 overruns:0 frame:0

RX bytes:290 (290.0 B) TX bytes:28452 (27.7 KiB)

the ip address is missing. How should I get the ip address then?

it looks like your board is configured to get IP via DHCP (as it should), but there is no DHCP server on your network. If so, either connect to a network with DHCP server, or configure for static IP
