Two types of IP Addresses
DHCP is used to assign IP addresses to
hosts or workstations on the network
Two types of IP addresses:
Static

Internet service provider (ISP) to be its permanent
address on the Internet
Dynamic
The temporary IP address is called a dynamic IP
address
Why is DHCP Important?
Important when it comes to adding a
machine to a network
When computer requests an address, the
administrator would have to manually
configure the machine
Mistakes are easily made
Causes difficulty for both administrator as well
as neighbors on the network
DHCP solves all the hassle of manually
adding a machine to a network
How does DHCP work?
When a client needs to start up TCP/IP operations, it
broadcasts a request for address information
