Egress IP Addresses

Egress IP Addresses​

If you need to allowlist Phase Two's outbound traffic — for an SMTP relay, an IP-restricted API, or your own firewall — use the addresses below for your cluster's region. These are the addresses your cluster sends traffic from, which are not the same as the addresses your users connect to.

Allowlist all three addresses for your region. Traffic may originate from any of them.

AWS US West (Oregon) us-west-2​

18.236.0.114

Changes to these addresses​

These addresses are static and we do not expect them to change. If they ever do, we will announce the change in a release notification before it takes effect.

Your egress addresses will change if your cluster is migrated to a different region.

If you are unsure which region your cluster runs in, or you need these addresses confirmed for a compliance review, contact support@phasetwo.io.
