Does the renewal of my web hosting plan include a renewal of my primary domain name?
Domain names renewal fees are normally NOT included in the hosting renewal fees. However, there are some cases in which you may not be charged renewal fee for a primary domain, as it was acquired as a part of a special hosting promotion. When a domain name renewal fee is due, you will see your domain listed in your Client Area > Billing > Renewals.
If the domain name is registered by another registrar, you should contact them directly and ask them for assistance.
