Static IP addresses

Introduction to Vapi static IP addresses

Vapi supports static IP addresses for outbound HTTP requests. When enabled, all HTTP requests from Vapi to your server will originate from a fixed set of IP addresses, allowing you to configure strict firewall rules and network security policies.

Why use static IP addresses

Static IP addresses provide an additional layer of security for your infrastructure by allowing you to:

• Control network access - Restrict incoming traffic to only trusted sources
• Simplify firewall rules - Define precise IP based access controls
• Meet compliance requirements - Satisfy security policies that mandate IP whitelisting
• Audit traffic sources - Verify that requests are genuinely from Vapi’s infrastructure

Vapi’s static IP addresses

When static IP addressing is enabled, all webhook requests from Vapi will originate from the following CIDR block:

• 167.150.224.0/23

Enabling static IP addresses

You can enable static IP addressing through the server object

Example

1
{
2
  "serverUrl": "https://your-server.example.com/webhook",
3
  "staticIpAddressesEnabled": true
4
}
