Why is DHCP preferred for use on large networks? Large networks send more requests for domain to IP address resolution than do smaller networks. DHCP uses a reliable transport layer protocol. It prevents sharing of files that are copyrighted. It is a more efficient way to manage IP addresses than static address assignment. Hosts on large networks require more IP addressing configuration settings than hosts on small networks.

It is a more efficient way to manage IP addresses than static address assignment.
