dhcp (dynamic host configurati

Short for Dynamic Host Configuration Protocol. Set of rules. Lets computer network administrators automate, centrally manage assignment of IP (Internet Protocol) addresses to network devices, used by a host computer to obtain IP address so can communicate with other host computers. Uses concept of lease -- time given IP address will be valid for a device. Addresses usually change periodically, connection cannot be obtained/maintained over internet. Using both static IP addresses, dynamic DNS helps establish consistent connection. Also supports static addresses, e.g. for computers running web servers, needing permanent IP address.
