Final answer:
To complete host mapping for a help center, configure the help center settings to add a custom domain, then update your domain's DNS records, specifically by adding a CNAME record. DNS changes take time to propagate, and testing afterward ensures successful mapping.
Step-by-step explanation:
To complete host mapping for your help center, you'll need to configure both your help center settings and your domain's DNS settings. First, check the help center platform, such as Zendesk or Freshdesk, for the option to add a custom domain. This setting is usually found in the administrative portal under 'Settings' or 'Domains'. You will be prompted to enter the domain name that you want your help center to be accessible from.
Next, you'll need to update your DNS records. Specifically, you will add a CNAME record pointing your custom domain to the help center's default domain. For example, if your help center domain is 'support.yourcompany.com', you would add a CNAME record for 'support' that points to 'yourcompany.helpcenter.com'. This ensures that when users visit 'support.yourcompany.com', they are directed to your help center.
After updating DNS settings, it typically takes some time for changes to propagate across the internet. Once propagation is complete, you should test access to your help center through the new custom domain to ensure that the mapping is successful and working properly.
