Various software-based solutions are described below.Īs a MAC address can be changed, it can be unwise to rely on this as a single method of authentication.
#WHY CHANGE NETWORK MAC ADDRESS SOFTWARE#
The appropriate software solution is dependent on the operating system installed on the computer. When a hardware-based solution is not utilized, the user who intends to change the MAC address must instead rely on a software-based solution. Type in the MAC address of your host computer. Go to Configure and click the Advanced tab and then Network address. These network cards usually come with a bootable CD-ROM that executes a utility that permits the user to change the MAC address burned into the EEPROM. Locate the Network Interface Controller (NIC) for your Dock (typically Realtek GBE Ethernet) and right-click it and select Properties from the menu that appears. When a device connects to the ISP, the DHCP server notes.
Other methods of changing the MAC address are permanent at least one network card manufacturer bundles networking hardware with software that allows the user to change the MAC address. Some Internet Service Providers (ISPs) use a MAC address to dedicate an IP address to a gateway device. Changing the MAC address in this way is not permanent: after a reboot, it will revert to the MAC address physically stored in the card. Similarly, some software licenses are bound to a specific MAC address.
Changing the MAC address of the new interface will solve the problem.
#WHY CHANGE NETWORK MAC ADDRESS INSTALL#
Some Internet service providers bind their service to a specific MAC address if the user then changes their network card or intends to install a router, the service won't work anymore. This can be useful for privacy reasons, for instance when connecting to a Wi-Fi hotspot, or to ensure interoperability. Although physical MAC addresses are permanent by design, several mechanisms allow modification, or "spoofing", of the MAC address that is reported by the operating system.
