Spouse I wont to use other hosting provider and I need change DNS Alias www.vsgp.com. How can I do this?

To change the DNS record for www.yourdomain.com you can use the Advanced DNS Manager tool. To access this you must first login to your Network Solutions account and choose the Domains->Manage Domains option from the left menu. Click on the domain in question if you have more than one, and click the edit button next to "Domain currently points to".

Alternatively you are able to change the Nameservers from this screen as well, and after choosing edit you can pick "Change Domain Name Servers" rather than Advanced DNS Manager.
