Overview of DHCP

Overview of DHCP


DHCP dynamically configures and uniformly manages network parameters of clients on a TCP/IP network.

DHCP uses the client/server model in which a client applies to a server for parameters, such as an IPv4 address, default gateway address, DNS server address, and WINS server address. The server then replies with configuration parameters according to configured policies. DHCP dynamic allocates IPv4 addresses and allows for configuration and management of other network parameters on a server before parameters are delivered to clients.


As the scale and complexity of networks have increased, the number of available IPv4 addresses is no longer sufficient. In addition, increased popularity of wireless networks and mobile devices mean that client locations and IPv4 addresses are liable to change. DHCP was introduced to automate the assignment of network parameters, including IPv4 addresses, to clients.

DHCP is developed based on the Bootstrap Protocol (BOOTP), which runs in a static environment where each host has a fixed network connection. For each host using BOOTP, an administrator must configure a specific BOOTP parameter file that keeps unchanged in a long period.

DHCP improves on BOOTP by:

  • Providing automatic allocation of reused network addresses and configuration options, which enables a PC to obtain required configurations by sending a request.
  • Dynamically assigning an IPv4 address to each host, instead of specifying an IPv4 address for each host.

DHCP dynamically manages and configures IPv4 addresses for clients in a concentrated manner. This simplifies manual configuration and enables enterprise users to adapt to frequent network changes.
