# Static IP

> Use Blacksmith runners with a dedicated static IP

## Overview

CI pipelines often interact with external services like databases and APIs that block requests from unknown IPs.
We offer static IPs for Blacksmith runners. Whitelisting these IPs in your external services would allow Blacksmith runners to access them securely.

## Basics

On purchasing a static IP, all of the organization's runners will use a dedicated, encrypted [WireGuard](https://www.wireguard.com/) tunnel to route network packets through a NAT gateway with a static IP.
The dedicated tunnel per NAT gateway ensures complete isolation of network traffic for that organization from other Blacksmith subnets.

### Setup

To enable static IPs for your organization, please contact us through [our support portal](https://app.blacksmith.sh/?support=open).
