Definition: IP Address vs. MAC Address

There may be broken links in this article, the GROK staff has been notified and is working to resolve the issue.

IP Address

An IP Address is used to identify a computer on the Internet or a local intranet. If computers share a specific local network, each of the computers will also share part of their IP Address. In other words, the similar IP Addresses may indicate that a computer is close. The following example illustrates what an (IP v4) IP Address may look like:


MAC Address

The Media Access Control (MAC) Address is used to identify Ethernet network cards or simply PCs that have built-in Ethernet. In other words, every computer that uses Ethernet will have a MAC address; however, it is important to remember that some Internet connections do not use Ethernet. Unlike the IP Addresses, computers that share a specific local network will not have MAC addresses that resemble one another in any way.
