The MAC address (also known as the hardware, ethernet or physical address) of the device you are trying to register is an important pice of information; it lets us identify the device and configure our switches and firewalls to allow connectivity. You can find instructions on how to determine your MAC address by going to our web page with instructions for Windows/PC systems or our web page for MacOS systems.
For MAC addresses for UNIX or Linux systems, contact firstname.lastname@example.org for assistance.
The MAC address is a unique hardware address set at the vendor's factory. It consists of 6 pairs of hexidecimal digits, typically separated by colons or dashes. Occasionally the pairs of digits are separated by spaces, and in some rare instances, there are no separators, just a string of 12 hexidecimal digits. The hex digitis may be upper or lower case; we ask that you supply all MAC addresses in a stanrdard format:
For example, we use ipconfig to obtain the MAC address of a new system, and it reports 00-B0-0D-81-4D-61. To put this into standard form, we change the dashes to colons, and make sure all characters are lower case, resulting in 00:b0:0d:81:4d:61. Some systems might have reported this number as 0:b0:d:81:4d:61. To convert that to our standard form, we would need to make sure that the two hex values that show up as single digits have their leading zeros added, so it too would be entered in the form as 00:b0:0d:81:4d:61.
