Explanation
An IP address beginning with 169.254.x.x is an APIPA address (Automatic Private IP Addressing). CompTIA A+ explains that APIPA is assigned automatically by Windows when the NIC cannot reach a DHCP server. This indicates the laptop requested an IP lease but never APIPA addresses allow only local subnet communication and cannot access the internet, because no default gateway, DNS, or valid subnet configuration is provided. Since all other employees can access the internet, the DHCP server is functioning generally, but it is not delivering an address to this specific laptop-possibly due to cable issues, Wi-Fi authentication failure, DHCP scope exhaustion, or NIC misconfiguration.
