Addresses you can move between servers

IPv4 and IPv6 addresses you can move between your servers, with reverse DNS you control and DDoS filtering on every address.

A floating IP is a public address that belongs to your account. Attach it to a Cloud Compute instance or a game server, and move it to another one when you need to. We sell IPv4 addresses and blocks, and single IPv6 addresses for Cloud Compute instances.

Each address stays on your account until you cancel it. You need a server in the same region to attach it to.

Technical specifications

The sizes come from what we sell today. Both families attach to a server in their own region, and differ in what they attach to and what they cost.

What you can order

• Sizes: IPv4: A single address, or a block where a region has one. IPv6: A single address. We sell no IPv6 blocks.
• Attaches to: IPv4: Cloud Compute instances and game servers. IPv6: Cloud Compute instances only.
• Region: IPv4: From a pool in the region of the server. IPv6: From a pool in the region of the instance. Fewer regions sell IPv6.

What it costs

• As an instance’s main address: IPv4: One IPv4 address is an instance’s primary address, and costs nothing there. IPv6: Never the primary address. It always bills at its own price.
• What comes with an instance: IPv4: A public IPv4 address, free as its primary address. IPv6: A /64 at no charge in a location with IPv6, which cannot move.

Protection

• DDoS Shield: IPv4: Included. IPv6: Included.

Addresses

• IPv4: A single address
• IPv4 blocks: Blocks of several sizes, where a region has one
• IPv6: A single address, a /128
• Usable addresses in a block: Fewer than the block holds, as the price list shows for each size

Placement

• At a time: A single address on one target. Each host of a block on its own

Network

• Reverse DNS: Set on each address, and on each host of a block
• DDoS filtering: DDoS Shield on every address, attached or not

What every floating IP includes

Each address comes with these, whichever server it is on. A tag says how each one comes.

Addresses

• Move it between servers (Included). Detach the address from one server and attach it to another, so the address players and visitors use stays the same.
• Choose the region (Included). Each region has its own pool of addresses. Order the address in the region of the server it goes on, because an address attaches only in its own region.
• For instances and servers (Included). A Cloud Compute instance can hold several floating IPs, IPv4 or IPv6. A game server holds one IPv4 address.

Network

• Filtered by DDoS Shield (Included). We filter DDoS attacks, floods of traffic meant to take a server offline, on every floating IP at no charge, attached or not.
• Reverse DNS (Included). Set the name the address points back to. Mail servers check it before they accept your email.
• Shield settings for each address (Included). Change the protection mode, rate limits and rules of one address, or apply a custom profile to several. DDoS Shield

Billing

• Free as an instance’s main address (Included). A single IPv4 address costs nothing while it is the primary address of a Cloud Compute instance. An IPv6 address always bills at its own price.
• An IPv6 /64 with each instance (Included). An instance in a location with IPv6 gets a /64 at no charge. It is routed to the instance and ends with it, so it cannot move. The IPv6 /64 of an instance

How it works, and what customers use it for

1. Order an address. Choose IPv4 or IPv6, the size and the region of your server, and we assign an address from that region’s pool.
2. Attach it. Attach the address to an instance or a game server in the same region from the dashboard.
3. Move it when you need to. Detach it and attach it to another server. The address stays on your account.

What customers use floating IPs for

Each one names what it takes and the guide that walks through it.

• Move a site to a new instance. Attach the site’s floating IP to the new instance, and visitors reach it at the same address. Its DNS records stay as they are. Uses: Cloud Compute and a floating IP. Attach and detach a floating IP
• A game on its default port. Attach a floating IP to a game server, and publish the game on its default port, so players type the address alone. Uses: Game servers and a floating IP. Manage server ports
• A mail server that others accept. Set the address’s reverse DNS to your mail server’s name, which receiving servers check before they take its mail. Uses: Cloud Compute and a floating IP. Set reverse DNS for a floating IP
• Several services on one block. Order an IPv4 block, and attach each host to a different instance or server in the region. Uses: A block of floating IPs. IP pools and regions

Limits

What a floating IP does not do.

Fixed limits

• Same region: An address attaches only to a server in its own region, so you need a server there first
• IPv6: A single address that attaches to Cloud Compute instances only. We sell no IPv6 blocks
• A game server: Holds one floating IP, IPv4
• Ports on a floating IP: Up to 16, from 1024 to 65535
• A block: Always bills at its own price
