Q.  What is DHCP?

A.  DHCP = Dynamic Host Configuration Protocol is an Internet protocol.  It resides in a DHCP server and clients that use the server.  Simply put, a DHCP server supplies Internet Protocol (IP) addresses when requested by client computers on a TCP/IP network that have TCP/IP configured to obtain their IP addresses automatically.  A DHCP server is configured to use a range of IP addresses known as its scope.  It automatically and dynamically manages the allocation of IP addresses within its scope.  IP addresses are assigned to clients under a lease arrangement that can be set for to expire after a given time.
