Explanation:

IP addresses beginning with 169.254.are calledlink-local addressesorAPIPA (Automatic Private IP Addressing)1.They are assigned by the computer itself when it cannot reach a DHCP server to obtain a valid IP address from the network2.This can happen for several reasons, such as a faulty router, a misconfigured network, or a disconnected cable3.

To troubleshoot this issue, the technician should check the network settings, the router configuration, and the physical connection of the computer. The technician should also try to renew the IP address by using the commandipconfig /renewin Windows ordhclientin Linux. If the problem persists, the technician may need to contact the network administrator or the ISP for further assistance.
