Adding an IP block

Find out how to order an IP block on your Private Cloud

Last updated 6th April 2022


An IP address block can be used to make your services available over the Internet.

This guide explains how to order and migrate an IP block for your Private Cloud.



To order an additional IP block for your Private Cloud, log in to your OVHcloud Control Panel. In the Hosted Private Cloud section, click on IP in the left column and then click on Order additional IPs. Then select your Private Cloud from the drop-down menu before proceeding to the next step.

Several fields will be required to create your IP block:

  • IP block size (from /28 to /24)

As a reminder, here is an array of IP addresses in a block, and the number of IPs that can be used:

Block size IPs in block IPs usable in OVHcloud
28 16 11
27 32 27
26 64 59
25 128 123
24 256 251

Please consult our guide "Using the OVHcloud Network plugin" to find out which IP addresses are reserved in a block as well as their use.

  • Country of IP block, important in some cases for the SEO of your services (an English-language website will have a better SEO in England if the IP is also English)
  • Network name (information visible in the Whois of an IP block).
  • Number of clients estimated (how many end clients will be hosted on these IPs).
  • Network description (information visible in the Whois of an IP block).
  • Use (information about the general usage (Web, SSL, Cloud...)).

There is a one time setup fee for an IP block that will be due before delivery.

IP block renewals will be free of charge.

After confirming the last step, you can view the order form for your IP block. If the order is in accordance with your wishes, you only have to pay it with the payment methods offered at the bottom of the page in order for it to be delivered.

The result will be in this form:

If you need to detach the IP block, you can use the following API call to move the IP into the "IP parking" section:

This call cuts the network on VMs that use the IPs in question.

You can track the IP block movement from your OVHcloud Control Panel in the Hosted Private Cloud part and then Private Cloud. Click on your Hosted Private Cloud service and then click the Operations tab.

The operation name is removeIpRipeBlock.

The IP will then appear in the IP parking.
