Please visit our [comparison page](https://eco.us.ovhcloud.com/compare/) for more information. - ADVANCE Gen 3 servers (powered by EPYC 4004) support 32 vMACs per server. - As of May 2025, this feature is available on the Scale and High Grade ranges. These ranges are also limited to 32 vMACs per server.   ## Requirements - A [dedicated server](https://us.ovhcloud.com/bare-metal/) that supports [virtual MACs](https://docs.us.ovhcloud.com/en/bare-metal-cloud/dedicated-servers/determine-if-dedicated-server-supports-virtual-mac-addresses.md) - An [Additional IP address](https://us.ovhcloud.com/network/additional-ip/) or an Additional IP block (RIPE) - Access to your [OVHcloud Control Panel](https://manager.us.ovhcloud.com/) or [OVHcloud API](https://api.us.ovhcloud.com/) - Your server must support virtual MACs (to determine this, consult [this guide](https://docs.us.ovhcloud.com/en/bare-metal-cloud/dedicated-servers/determine-if-dedicated-server-supports-virtual-mac-addresses.md)) **Note:** If you are not familiar with the OVHcloud API, please refer to our [First Steps with the OVHcloud API](https://docs.us.ovhcloud.com/en/manage-and-operate/api/first-steps.md) guide.   ## Instructions **Warning:** **NOTE:** If an IP block has been moved to the vRack, it is no longer assigned to a physical server. This means you cannot assign a virtual MAC address to any IP. ### Assign a MAC address #### Via the OVHcloud Control Panel From the [OVHcloud Control Panel](https://manager.us.ovhcloud.com/), select `Bare Metal Cloud` from the top navigation bar. In the left-hand menu, click `Network` and then `IP`. Use the filter functions beneath **My public addresses and associated services** to limit your results to Additional IPs. To the right of your Additional IP address (or block), click the _more options_ `...` button and choose `Add a virtual MAC`. In the pop-up window, select a **Type** from the dropdown list, enter the **Name of virtual machine**, and then click `Confirm`. **Note:** **Type:** Refers to the virtual MAC address type ('vmware' will be a MAC address made for the VMware ESXi system, while ‘ovh’ will be for any other type of virtualization system). **Name of virtual machine:** Refers to the desired name for the virtual MAC address, in order to make it easy to identify this IP/MAC pair in the future. **Note:** Do not forget to assign the virtual MAC address created in your virtual machine configuration.   #### Via the OVHcloud API Use the following API call: [POST /dedicated/server/{serviceName}/virtualMac/{macAddress}/virtualAddress/{ipAddress}](https://api.us.ovhcloud.com/console/?section=/dedicated/server&branch=v1#post-/dedicated/server/-serviceName-/virtualMac/-macAddress-/virtualAddress/-ipAddress-)   ### Delete a MAC address **Warning:** **NOTE:** When a MAC address is deleted, it will not be recoverable. #### Via the OVHcloud Control Panel To remove a virtual MAC address associated with an additional IP, you must first connect to your [OVHcloud Control Panel](https://manager.us.ovhcloud.com/). Once connected, go to the `Bare Metal Cloud` section and open the `IP` menu. Select the correct server so that the additional IP (or IP block) attached to it appears. Finally, click on the _more options_ `...` button on the right, then click `Delete a Virtual MAC`. In the pop-up window, click `Confirm`.   #### Via the OVHcloud API Use the following API call: [DELETE /dedicated/server/{serviceName}/virtualMac/{macAddress}/virtualAddress/{ipAddress}](https://api.us.ovhcloud.com/console/?section=/dedicated/server&branch=v1#delete-/dedicated/server/-serviceName-/virtualMac/-macAddress-/virtualAddress/-ipAddress-)   ### FAQ _What happens if I move a block with vMACs on a 3rd generation Advance server (powered by an EPYC 4004 Series processor) that already has 32 vMACs?_ The block will not be moved. For example, if you try to move a block of four IPs with different vMACs attached on a server that already has 30 vMACs, the block will not be moved because the total vMACs would be greater than the 32 vMACs allowed.   ## Go further Browse all the [Dedicated Servers guides](https://docs.us.ovhcloud.com/en/bare-metal-cloud/dedicated-servers/landing-page-dedicated-servers.md).
