It is the combination of the OUI and the vendor-assigned number that ensures that no two network adapters have the same MAC address. The vendor-assigned portion of the MAC address is just that, the alphanumeric identifier assigned by the vendor. The OUI is administered by the IEEE and identifies the vendor of the network adapter. The OUI is 00-08-a1, and the vendor-assigned number is 08-c8-13. This MAC address is used for the Fast Ethernet adapter on the computer in question. The MAC address on a computer might look like this: 00-08-a1-08-c8-13. It is 48 bits (6 bytes) long and is made up of two parts: the organizational unique identifier (OUI) and the vendor-assigned address, as illustrated in Figure 5-1. For this discussion of LAN environments, the physical address (also known as the Media Access Control address) is relevant.Ī MAC address is the physical address of the device. Two types of addresses are found in a network: the logical (OSI model Layer 3, network) and the physical (OSI model Layer 2, data link). To be a part of any network, you must have an address so that others can reach you. By a given MAC address/OUI/IAB, retrieve OUI vendor information, detect virtual machines, manufacturer, locations, read the information encoded in the MAC, and. Please feel free to contact us via our Contact Us page with any questions, improvements, requests, ideas, or anything at all you may have.The MAC address is the unique serial number burned into each network adapter that differentiates the network card from all others, just as your house number is unique on your street and identifies your home from all others. Our current site will continue to operate without the API enabled and once the beta site goes live, all (correct) API queries will be backward compatible with the new website.
We will get back to you with a link when the beta is live. We have tested the new site a few times during off-peak hours and the results are extremely promising! If you would like to help test our beta site, please Contact Us and let us know you are interested in the beta. Since we have been subject to abuse of our API from several large companies and smart phone app creators who have incorrectly implemented our API, we have essentially been DDoSed for the past few months.
First we would like to thank all our loyal users, especially the ones who have donated!
