When to set your domain’s name servers
If you already own a domain that you purchased from a different registrar or hosting company, you can change the name server (DNS) settings for the domain so they point to A2 Hosting’s servers. (Billing and domain administration remain with the domain’s current registrar.)
Setting your domain’s name servers
When you change a domain’s name server settings, you must specify at a minimum a primary name server and a secondary name server. This ensures that there is at least one alternate server available to provide DNS information about your site if one of the servers is unavailable.
The correct name servers for your domain depend on the type of account you have, and which A2 Hosting server hosts your account. The Welcome e-mail you received when you became an A2 Hosting customer provides the name servers that you should use for your account.
For example, shared hosting accounts use ns1.a2hosting.com, ns2.a2hosting.com,ns3.a2hosting.com, and ns4.a2hosting.com as their name servers.
Almost all domain registrars provide a control panel where you can manage a domain’s name server settings. If you are unable to make these changes, contact the domain’s registrar and ask them how to change your domain’s name server or DNS settings.
