There is nothing wrong with the IP addresses. This is who they are registered to:

So why would the geolocation services say something different?
They rather want to know where they are being used than who they are registered to. They may be looking at what clients are seen from this IP range. They may have some access to information about, what sites those clients are accessing, what language settings they are using, which locale information they are looking up on various sites. And based on that try to deduce where those IP addresses are being used.
Since this IP range is used for a datacenter, you usually don't find many end users coming from that range of IPs. Any HTTP clients running in a datacenter tend to not be a browser, but rather just downloads of software.
But if there happen to be a proxy or a VPN service hosted in the same datacenter, then there could be some end users coming through that. And if lots of those are from Asia, that might be enough that the geolocation services have figured it out and marked that IP range as being used in Asia.
You shouldn't worry about it, it's not your server which has a problem it's the geolocation services.
As for the "Services" part, they have a link explaining it. As best I can tell, that feature of their site is simply not working.
