How much bandwidth do you provide? What is the transfer limit?

Your server comes with up to 2Gbit/s of internet bandwidth depending of your server. Checkout the pricing page to find the exact value. The internal bandwidth is only limited by the speed of your network card.

There is no transfer limit, transfer is unlimited.

What is a reserved IP address?

A reserved IP address is an IP address which you hold independently of any server. You can attach it to any of your server and do live migration of the IP address between your servers.

Be aware that attaching a reserved IP address to a server will remove the previous public IP address of the server and cut any ongoing public connection to the server.

Can I have a firewall?

Yes! You have the possibility to create security groups for your instances.

Using security groups, you can create stateless or stateful rules dropping or allowing incoming traffic from specific sources. You can then create your own private infrastructure by disabling the public IPs of your servers. To create security groups, refer to our official documentation.

Important: If you create a stateful security group, it cannot be attached to a baremetal server. In addition, if you already have a stateless security group attached to a baremetal server, you will get an error while trying to switch that security group to stateful.

Are security groups updated instantly?

On all Virtual Cloud Servers Security Group settings are updated automatically within a few minutes after you made them. No reboot is required.

On BareMetal Cloud Servers a hard reboot of the instance is required to update the Security Group settings.

Do you offer IPv6?

Yes, our C2 and Virtual Cloud Servers come with native IPv6 connectivity. Currently, we only provide IPv6 tied to the physical server or to the V, meaning that your IPv6 will change if you stop your server. We’re working on providing more flexibility on our IPv6 connectivity, stay tuned for improvements on our IPv6 stack!

Check out our blog post to configure your IPv6 on your C2 or Virtual Cloud Servers!

Do you offer protection against DDoS attacks?

Our network is protected by’s standard anti-DDoS system.

Why do I have a private IP?

We chose to use NAT for IPv4 addresses.

We use the NAT to get movable IP addresses which help us face the shortening of IPv4 addresses.

We implemented a custom solution to provide line-rate NAT.

What is the advantage to have a server without public IP?

You have the choice to change the network configuration of a server and remove its public IP.

This feature gives you more control, you can put your servers into our private subnet and not expose them to the internet (e.g Databases, Backups). You can then use security groups to only let specific host to get an access to them. It allows you to optimize your costs and to fight the global IPv4 shortage.

I cannot send any email.

To avoid spam, remote mail ports (25, 465, 587) cannot be reached from our infrastructure. If you need to open the mail ports to send e-mail, you can go to the advanced options section of your server and change the security group configuration:

  1. On the left panel of the Control Panel, click on “Security”
  2. Select the Security group you want to unblock remote mail ports
  3. Set “Block SMTP” to No.
  4. The Security group settings will be updated immediately on all our Virtual Cloud Servers. BareMetal Cloud Servers require a hard reboot to apply the new configuraion.

IMPORTANT: Your account needs to be validated to perform this operation. To get your account reviewed, please contact our assistance.

Can I edit the reverse DNS of my IP address?

Yes! You can edit the reverse DNS of your reserved IP address.

How can I choose the physical position of my server in your datacenters?

We currently rely on internal heuristics to choose the exact place we’re going to spawn a new server. Having the total control of the positioning allow us to select the best place to start a server from, optimizing for network proximity and resiliency.

In the future we might expose some of the underlying details so you’ll be able to gain more control on placement preferences. In the mean time a server’s physical position in our datacenter is available through the server API via the location field . It shows the complete platform_id > chassis_id > node_id coordinates of your server.

Can I attach multiple IPs to a server?

We do not support assigning multiple IP addresses to a single server.

Can I register IPs under my company name?

It is not possible to register, under your company, the IP address you reserve.

We are not an IP address broker. IPs we propose on our platform are owned and registered by Scaleway.
