Can someone please tell me what Host this nameserver belongs to...
NAMESERVE.NET

thanks!

It traces near Bellevue, Washington.

The network DNS are
NS1.LIGHTREALM.NET 207.159.128.2
NS2.LIGHTREALM.NET 207.159.128.10
NS3.LIGHTREALM.NET 207.159.153.114

If you go to http://WWW.LIGHTREALM.NET you get to HostPro's Order Configuration Confirmation. They either have a dedicated or colocate with HostPro or are resellers.

It is Host Pro themselves. I have a few virtual servers by them and this is the DNS you need to setup in your Domain Name settings.
