# Egress IPs

This page documents the egress IP addresses reserved for Zaia.

Customers and partners that use IP allowlists should allow the egress IPs listed on this page.

### Concepts

#### Egress IP

Unline the ingress IP which is the IP that, for example, the api.endless.zaia.app domain points to, the **egress IP** is the public IP address used by a service when it sends outbound requests to external systems.

In this case, when Zaia connects to a customer API, partner service, private integration, firewall, or third-party platform, the external system may see the request coming from one of the egress IPs listed on this page.

***

#### IPv4 and IPv6

IP addresses can be represented in two main formats: **IPv4** and **IPv6**.

**IPv4** is the older and most widely supported format. It is commonly used by firewalls, security groups, allowlists, APIs, and network configurations.

Example:

> `209.71.78.101`

**IPv6** is a newer format created to support a much larger number of addresses. Some modern services and networks support IPv6, but not every external system accepts IPv6 allowlists.

Example:

> `2a09:8280:e615:1:0:92:2c77:0`

When configuring access to external systems, use the IP version supported by that system.

If the external system only supports IPv4, allowlist only the IPv4 addresses.

If the external system supports both IPv4 and IPv6, allowlist both versions when possible.

Requests may be routed through farther regions, so when registering the IPs above in the allow list, make sure to setup every region regardless of your service's closest region.
