# Relay IP addresses and domains

#### Overview

For enhanced network security, we provide a predefined range of outgoing IP addresses and domains that you can allowlist. This ensures secure communication and reduces potential vulnerabilities. Note that these IP addresses and domains cannot be managed directly within your account settings. To implement this, please coordinate with your security team to properly configure the allowlist for your network.

#### IP addresses and domains

Relay is solely hosted in Asia Pacific (Sydney) ap-southeast-2.
