IP FO can be used in several ways:
- Multiple IPs on the same interface. In this case, there will always be a default IP, but applications(both client and server) can choose to use a specific IP either for outbound our inbound traffic.
- Only one IP on the NIC, but with OpenVPN or similar along with IPtables rules which makes some kind of NAT. This is specially useful when your ISP doesn't offers you a public static IP.
- If you have a full server, you can have multiple VMs, each one with a different IP.
However, there's a restriction, both for servers & VPS: you can only have FO IPs from the continent your server/VPS is located. That is, if your server/VPS is located in one of OVH French datacenters, you can get FO IP geolocated in ES, GB, FR, PL, IT, PT, and some more, but you cannot get FO IPs geolocated in CA or US; same way, if your server/VPS is located in OVH CA datacenters, you will only be able to get FO IPs geolocated in CA or US, not from european countries. The only exception to this rule is when using vRack on the serve ranges which support it, having servers in both CA & FR, and assigning IP blocks to a VLAN; but I've never tried it.
Switching between outbound IPs depend on the software you use. Squid, for example, has a configuration param which allows you to set the outbound IP, so you can have multiple Squid instances with different outbound IP. Other proxy software can or not support similar or better features.
Just a note. Open proxies are forbidden by OVH TOS. Private proxies are not a real problem.
