An IP address (Internet Protocol address) is a unique address that certain electronic devices currently use in order to identify and communicate with each other on a computer network utilizing the Internet Protocol standard (IP)—in simpler terms, a computer address.

Any participating network device—including routers, switches, computers, infrastructure servers (e.g., NTP, DNS, DHCP, SNMP, etc.), printers, Internet fax machines, and some telephones—can have its own address that is unique within the scope of the specific network.

Some IP addresses are intended to be unique within the scope of the global Internet, while others need to be unique only within the scope of an enterprise.

The IP address acts as a locator for one IP device to find another and interact with it. It is not intended, however, to act as an identifier that always uniquely identifies a particular device. In current practice, an IP address is not always a unique identifier, due to technologies such as dynamic assignment and network address translation.

Definition of: static IP address (Ip yang disetkan oleh administrator)

A permanent numeric identification assigned by the network administrator to a node in a TCP/IP network. Static IP addresses are used for shared resources such as Web servers and Webcams.

ISPs assign static IP addresses to the Internet connections of their large business customers, which command a premium over dynamic IP addresses. Contrast with dynamic IP address. See IP address.


Definition of: dynamic IP address (Ip yang diberi @ disetkan oleh modem.)
A temporary numeric identification assigned to a node in a TCP/IP network. When computers and devices in the network are turned on, they are assigned an IP address by a DHCP server.

ISPs typically assign dynamic addresses to the Internet connections of their residential and small business customers, which are less expensive than static addresses. That means the IP address to the outside world in a cable or DSL modem may change every month, every day or even every hour (see DDNS). Contrast with static IP address. See IP address and DHCP.
