DHCP

DHCP is a foundational network protocol that operates quietly behind the scenes yet plays a pivotal role in the functioning of modern computer networks. It’s fundamental for both small and large-scale network environments, serving as a dynamic orchestrator of IP address assignments and network configurations. DHCP streamlines the process of connecting devices to a network by automating the allocation of vital network parameters.

Consider an enterprise network that has about 1,000 network devices, maybe 600 wireless APs, 1,500 servers, and 10,000 employees, each with two devices (laptop and cellphone) and 10 regional locations.

My questions are as follows:

  • How would you go about assigning IP addresses to these devices and managing them?
  • Would you assign an IP address to each employee and have them configure a corporate laptop?
  • Would you statically assign an IP address to all your routers/switches, firewalls, servers, and SAN devices from the IP same...
