Information about Dynamic Host Configuration Protocol.
What is DHCP all about?
Dynamic Host Configuration Protocol is a client/server protocol that provides an IP host with its IP address and other configuration such as subnet mask and default gateway. It also allow hosts to obtain necessary TCP/IP configuration information from a DHCP server.
Benefits of DHCP
* Reliable IP address configuration
* Reduced network administration
Why use DHCP
Every device on a TCP/IP-based network must have a unique IP address to access the network and its resources. Without it, IP addresses must be configured manually for new devices and/or modified devices, or when devices are removed from the network.
With DHCP, the process are automated and managed centrally. Meaning, whenever there is a new device the free IP address will be assigned to it, and when no longer in use will be returned to the pool of IP addresses for reallocation.
