Dynamic Host Configuration Protocol
protocol for assigning dynamic IP addresses to devices on a network.
Devices can be your computer, router, wireless access point, telephone,
even your fridge!!
With dynamic addressing, a device can have a
different IP address every time it connects to the network. DHCP
also supports a mix of static and dynamic IP addresses.
assignment of IP addresses makes the life of a network administration
easier because the DHCP server (called a server but is generally a
software program running on a server) keeps track of IP addresses rather
than requiring an administrator to manage the task. This means that a new
device can be added to a network without the hassle of manually assigning
it a unique IP address.
Generally ISPs use dynamic IP addressing for
dial-up and broadband users.
