IP Addresses (Dedicated IPv4)

A dedicated IPv4 address is a public address of your own, taken from the region's pool. It stays in your organization until you release it, and you can move it from one server to another.

📌

Floating IPs are not available in veloxa-us-east-1 yet. What this page describes is the dedicated IPv4 add-on, managed on the IP Addresses page in the console and through API v2. Every server is also reachable without one, through a block of ports on the region's shared IPv4 address — see Shared & Dedicated IPv4.

When to Use a Dedicated IPv4 Address

  • Standard ports — serve on ports 80 and 443, or any other port, over IPv4
  • Stable DNS — point your domain's A record at the address; move it to a replacement server without touching DNS

Request an Address

In the console, use the IP Addresses page. With the API, request an address and, optionally, the server to route it to:

POST /api/v2/ips
{ "server": "web-1" }      // optional

# Response
{
  "data": {
    "id": "<ip-uuid>",
    "address": "203.0.113.42",
    "server": "web-1",
    ...
  }
}

If the pool has no free address, or you already hold as many as your plan allows, the request is refused. List your addresses with GET /api/v2/ips.

Attach to a Server

PUT /api/v2/ips/<ip-uuid>/server
{ "server": "web-1" }

The address is routed to the server, which then has to answer on it: add it to the server's network interface (see Dedicated IPv4).

Detach / Move

# Detach without releasing
PUT /api/v2/ips/<ip-uuid>/server
{ "server": null }

# Move to a different server
PUT /api/v2/ips/<ip-uuid>/server
{ "server": "web-2" }

Release an address you no longer need from the IP Addresses page. Both API calls need an API key with instances:write.

Pricing

An IPv4 address from the pool is a dedicated IPv4 add-on: $2 a month per address by default, billed hourly from the hour it is assigned to your account until you release it, attached to a server or not. The console shows the current price on the IP addresses page. How many addresses an account may hold at once depends on its plan. See Billing.
