Why do we ask for your MAC address

Thank you for wanting to evaluate or buy a Cradle Product.

As part of the order or evaluation process, you will need to enter the MAC Address of the specific computer which you are going to install Cradle onto. This will be used to create part of the security code which ties your Cradle installation to that specific computer.

If you enter the wrong information in the field for the Host ID/MAC address, you may not get a security code, or the security code may not work.

To find your MAC address for Windows installations:

You may either:

  • Open the CMD prompt in Windows and type ipconfig /all and the MAC address is the physical address of the ethernet controller of the computer you are installing on:
  • Or use the getmac command

We recommend using the MAC address of a wired ethernet adapter.

The MAC address is a 17 character code in the format of 6 hexidecimal pairs separated by colons: or hyphens-

00:00:00:00:00:00 or 00-00-00-00-00-00

 

For Linux installations:
