A unique and valid MAC address is a MAC address assigned by a vendor and burnt into the port or card of a device.

The address must be:

• Vendor-issued and universally administered – MAC addresses cannot be administratively or locally assigned and must have the Universal bit set in the address
  • A vendor/universal MAC address will have the 2nd character as “0” “4” “8” or “C”. Examples:

    x0-xx-xx-xx-xx-xx

    x4-xx-xx-xx-xx-xx

    x8-xx-xx-xx-xx-xx

    xC-xx-xx-xx-xx-xx

• Unicast – Multicast MAC addresses are not permitted (addresses which meet the above 2nd character restrictions are not multicast)

And must not be:

• Currently assigned to or in use by any other customer or device on our network
• Cloned, spoofed, or randomly generated addresses of a device that is not in the customer’s direct possession
  • By providing us with your MAC address, you certify that the device originally assigned that address is in your direct possession. Using a cloned or spoofed address is a violation of Omni Fiber’s Terms of Service and may lead to service suspension or termination.
• Assigned for use by a protocol – MAC addresses assigned to protocols (e.g., beginning with 00-00-5E or 00-00-0C) are not permitted. This includes MAC addresses for most virtual IP and redundancy protocols such as VRRP and HSRP
• All zeros (00-00-00-00-00-xx) or a derivative thereof
• Currently assigned to or in use by any other customer or device on our network

Omni Fiber reserves the right to revise these requirements, review and deny all MAC addresses registered by a customer, and/or block any MAC address requested for use without notice.

If you require non-standard MAC addresses for your equipment, please contact us to discuss our Dedicated Internet plans, or see the question “I can’t use DHCP, but don’t what Dedicated Internet! What can I do?”
