After you have set up your domain as described in Set Up a Web Store Domain, you need configure your DNS settings. Configuring DNS settings means that you are instructing your domain name provider to point your domain name at the NetSuite website hosting servers.
In non-technical terms, configuring DNS settings is like setting up a mail redirection when you move house — you inform the post office to send all letters addressed to your old home address (your domain name) to your new address (NetSuite hosted domain). The people sending you letters use your old address but you will receive them at the new address. The file the post office holds for you containing information on where to send your letters is the equivalent of DNS settings.
Changing DNS configuration affects the ability to navigate to your site. It should be changed by someone with DNS setup experience, or consult with your domain provider.
In most cases, your domain provider can redirect your domain name by using the CNAME record (Canonical Name record) to designate your domain name as an alias of the NetSuite hosting domains assigned to your account. You can obtain the CNAME for your domain from the Domains subtab of the Web Site Set Up record, and the Setup > SuiteCommerce Advanced > Domains record.
Configuring DNS settings with your domain name provider is a task that you complete outside of NetSuite.
Obtain the CNAME (Alias) for a Domain
You can copy the CNAME record for your domain from the CNAME (Alias) column on the Domains subtab of the Web Site Set Up record, or from the Setup > SuiteCommerce Advanced > Domains record.
The CNAME (Alias) assigned to each domain in each NetSuite Account is unique.
Set Up a CNAME Record
Log into your domain provider website to manage DNS settings and to set up CNAME records. This is a task that you must complete outside of NetSuite.
Each domain provider has an online help system that gives detailed instructions for adding and editing CNAME records. Instructions vary depending on the domain provider. Make sure that you have copied the CNAME (Alias) displayed in your NetSuite account to use in DNS configuration settings with your domain provider.
If you use the same domain name for both your website and for email hosting, you cannot use a CNAME record to point your website domain to NetSuite. You must set up an A record for your website domain. For more information, see Website Domains and Email Hosting, in particular, the procedure on how to set up an A record.
Add or Change a Domain Name
Each time you add a new domain name in NetSuite, you must use the CNAME (Alias) displayed for that domain to configure DNS with your domain provider. If you change a domain name that you have entered in NetSuite, the corresponding CNAME (Alias) also changes. In this case, you must update DNS settings with your domain provider with the new CNAME (Alias).
