The ifconfigIPV4 address is missing.

The ifconfigIPV4 address is missing-Linux general technology-Linux technology and application information. The following is a detailed description. The workstation has two NICs, one of which (eth0) is set to a fixed IP address, and the other (eth1) is set to a dynamic IP address.
Now you want to view the eth1 address and run ifconfig under root to obtain the following information.
It can be seen that the desired inet addr information is not displayed in eth1.
Why? How can this problem be solved?
