What Hypervisor do you use?
We run the excellent XEN Hypervisor across all our cloud platforms. Our physical nodes are all HP Blades - specifically BL460C Gen8 Blade.
You can add any number of IPs to your Resource Pool and assign them to your Servers. We offer IPv4 and IPv6 addresses. If you would like a Reverse DNS setup on one or more of your IPs you can open a support ticket with the request and we will make the change right away for you.
