iwStack and armorshark have cloudstack/openstack things, so maybe they offer those features.
Edit
Nevermind, my Technical Translate misunderstood OP's question.
Well, an IP address I can move between two VMs in the same datacenter/location.
Failover IP?
Yes, that is what Hetzner & OVH call it. I'm basically trying to avoid jumping to buying a 3 server cluster of actual machines [from OVH's SYS brand] and sticking with VMs instead.

That might work but that isn't a VPS provider as far as I can tell?

OpenStack, Montreal, DO/Vultr pricing... 1$/IP
Rage4 is not a VPS provider, they provide anycast IP services that you can use in tandem with any VPS or dedi provider. Thought it many have worked for you... soon ;0
Fair enough. I'll wait until I can see the prices and decide. I'm not sold on Anycast for anything that needs functional sessions tho.
I thought they might but they told me they didn't when I signed up this weekend.
Are you wanting floating ip's in the same location for failover? If so, why not use heartbeat/pacemaker/drdb?
If I cannot move an IP address from Box A to Box B in the same DC, what happens when Box A fails? I'd have to update the DNS with the TTL delay that would create which is what I'm trying to avoid.
I don't want to have a single point of failure other than the network/power/etc for the DC if I can avoid it.

Yes, Rackspace calls what I am talking about a "shared IP" but last time I checked they weren't LEB budget range.

$30/month minimum
I know how to implement it. The issue is finding a LEB that supports it versus going to a bargain Dedicated provider [e.g. Online.NET] and picking up 2 Atoms + the shared IP.
Since this is primarily a hobby project and professional practice, my total budget is like USD $50/month with a preference for the cheapest option that will be up 99% of the time.
A shared ip is just a normal ip when its comes to heartbeat. Not sure if you can do this on openvz easily (not sure if venet causes issues) but should be able to do this with a KVM host easily as you need to assign the ip's yourself generally.
Just think of it as this, VPS-B pings VPS-A, if no reply then VPS-B will assign the ip essentially taking over the ip. Nothing special about it.
If I was hosting the VMs, yes. That doesn't mean I can just capture the IP address on a new instance on someone else's infrastructure that I don't control and have it route correctly.
I know it hasn't on the provider's I've used in the past.
If your using KVM, you usually assign the ip's yourself, you get given an ip and you assign it yourself. I don't see why any KVM provider wouldn't be able to allow you to do this, i've done it before on rented VMs.
If you would tell the OP where you did that, and it worked, it would answer his original question
There's a feature in SolusVM that is labeled prevent IP stealing or somesuch. That pretty much puts the clamps on it.
