When testing against another origin, you may see either an IPv4 or IPv6 address. Gateway has no control over whether connections are made over IPv4 or IPv6. Some origins are only available over IPv4, while others are only available over IPv6. When both protocols are supported, the decision is made by the operating system and browser on the client device. For example, Windows will by default [favor IPv6](https://docs.microsoft.com/en-us/troubleshoot/windows-server/networking/configure-ipv6-in-windows) over IPv4.

Enterprise users can use their own authority-provided IPv4 and IPv6 addresses as dedicated egress IPs. Gateway supports bringing your own IPv4 and IPv6 addresses.

After you onboard your IP addresses, the IP addresses will appear when you create a [egress policy](/cloudflare-one/policies/gateway/egress-policies/) and choose **Use dedicated egress IPs (Cloudflare or BYOIP)** as the [egress method](/cloudflare-one/policies/gateway/egress-policies/#egress-methods). BYOIP dedicate egress IPs do not support [IP geolocation](#ip-geolocation).

- **Dedicated Cloudflare egress IPs** uses the primary IPv4 address and IPv6 range selected in the dropdown menus. You can optionally specify a secondary IPv4 address in a different data center. If the primary data center goes down, Gateway will egress from the secondary data center to avoid traffic drops during reroutes. There is no need for a secondary IPv6 because IPv6 traffic can egress from any Cloudflare data center. To learn more about IPv4 and IPv6 egress behavior, refer to [Egress locations](/cloudflare-one/policies/gateway/egress-policies/dedicated-egress-ips/#egress-location).
