DHCP

Intro
Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway.

Usages:
Computers use the Dynamic Host Configuration Protocol to request Internet Protocol parameters from a network server, such as an IP address. The protocol operates based on the client–server model. As of 2011, modern networks ranging in size from home networks to large campus networks and regional Internet service provider networks commonly use DHCP.

Advantages:

 * Safe and reliable configuration.  DHCP minimizes configuration errors caused by manual IP address configuration, such as typographical errors, as well as address conflicts caused by a currently assigned IP address accidentally being reissued to another computer.
 * Reduced network administration.

Disadvantages:
·     When client make query to DHCP server (DHCP Discover) it is UDP query it consume more bandwidth. When DHCP server is unavaliable client unable to access entrprises network.
