Understanding Network Addresses
This interactive lesson explains how network addresses work by using the analogies of street addresses and personal names. Similar to the way your street address changes if you move to a different neighborhood, a device's Internet Protocol address (also called an "IP address" or "logical address") changes when it is moved to a different network. In contrast, your personal name (for example, "Jane Doe") does not change if you move to a different part of town. A device's media access control address (also called a "MAC address" or "physical address") is "burned in" and does not change.
