How to set the name servers for a domain to point to A2 Hosting

This article provides information about how to set up a domain's name server settings to work with A2 Hosting's servers.

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.)

If you registered your domain directly with A2 Hosting, the name server settings are already configured. No further action is required on your part.

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.

Please note that this method does not apply to Dynamic VPS hosting, as DNS does not come preinstalled on these servers.

The correct name servers for your domain depend on the type of account you have, and which A2 Hosting server hosts your account. You can view the name server information for your account on the A2 Hosting Customer Portal at Nameservers and their IP addresses are listed in the Product Details of each product.

For example, shared hosting accounts use,,, and 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.

When you change a domain's name server settings or register a new domain, it generally takes 24 to 48 hours until the changes take full effect. This delay, known as DNS propagation delay, occurs with all hosts and is beyond our control. Therefore, until your domain fully resolves you cannot do the following:

  • Visit your web site by going to the URL, where represents your domain name. In the meantime, however, you can view your web site using shared URLs or a custom hosts file. For information about how to do this, please see this article.
  • Access your e-mail accounts. POP3, IMAP, SMTP, and webmail will not work until DNS propagation is complete.
