The rightmost digits of a MAC address represent an identification number for the specific device (S).
Among all devices manufactured with the same vendor prefix, each is given their own unique 24-bit number.
Administrators can configure their router (assuming it supports this feature, as many do) to use the cloning option and enter the MAC address of the old gateway into the configuration screen.
When cloning isn't available, the customer must contact the service provider to register their new gateway device instead.
Our simple to use RESTful API makes it easy to implement into any application you are building.
Before a manufacturer can build Ethernet products, it must ask the IEEE to assign the manufacturer a universally unique 3-byte code, called the organizationally unique identifier (OUI).Please feel free to contact us via our Contact Us page with any questions, improvements, requests, ideas, or anything at all you may have.Especially if you have any improvements or feature requests for the new site, we will accomidate and pack as many features as we can into the new site before it goes live! We have a free, simple to use RESTful API available for you to use in your own applications!Vendors often possess many prefix numbers associated with their different products.For example, the prefixes , :9C and 68:7F:74 (plus many others) all belong to Linksys (Cisco Systems).Zig Bee wireless home automation and other similar networks based on IEEE 802.15.4, for example, require 64-bit MAC addresses be configured on their hardware devices.TCP/IP networks based on IPv6 also implement a different approach to communicating MAC addresses compared to mainstream IPv4.IP networks manage the conversion between IP and MAC addresses using Address Resolution Protocol (ARP).The Dynamic Host Configuration Protocol (DHCP) relies on ARP to manage the unique assignment of IP addresses to devices.TCP/IP networks use both MAC addresses and IP addresses but for separate purposes.A MAC address remains fixed to the device's hardware while the IP address for that same device can be changed depending on its TCP/IP network configuration.
