The first thing you need to do is log into your Networks Solutions account (or whatever domain company you choose) and change the DNS Nameserver. You will keep your current domain name at network solutions (godaddy, enom, …etc) , but you will have a different hosting provider like Seattle Web Hosting at NinjaCloudHost.com
So Here is a photo to help you change your hosting company over to NinjaCloudHost.com -Always remember! Never share your Network Solutions domain username and password with anyone. A domain name is like a phone number, you ‘usually’ keep the same phone number forever (and ever). A web hosting company is like a phone carrier (AT&T, T-Mobile, Sprint) you might change carriers every 5 years, or they might go out of business so always protect and keep that domain name under your name.
