Final answer:
Without DHCP, networking equipment requires a static IP address, along with manually configured subnet mask, default gateway, and DNS server addresses to ensure proper network connectivity.
Step-by-step explanation:
When DHCP (Dynamic Host Configuration Protocol) is not used in a network, the information attribute of great value for networking equipment is a static IP address. DHCP typically provides automatic IP address allocation to devices on a network, so without it, each device must be assigned a unique static IP to ensure proper network communication and avoid address conflicts. Along with the IP address, other related information such as subnet mask, default gateway, and DNS server addresses must be manually configured to provide full network connectivity and internet access. This process involves a network administrator entering these details into the network settings of each device.
