When having a website hosting at one provided, and a domain name registered at another provider – for example gandi.net or godaddy.com – it is necessary to add the domain name to the list of Addon Domains (or external domains), in order to have requests from that URL addressed to defined hosting.
In below example, domain name lifetravelsv.com have been registered at gandi.net, while web hosting is provided by the excellent ex2 hosting
In the cPanel administration interface, open the Addon Domains menu. There, fill in the new domain name, subdomain, and document root – for example, all with the name of the domain to add, like lifetravelsv.com
And that’s all ! The new addon domain should now appear in the list, and it can there be modified if necessary.
