Addon domain slot count will be shown on order if the web hosting package allows hosting multiple fully functional domains. Generally, for each fully functional domain, a separate web hosting package has to be purchased. Radicenter provides a convenient and cost-effective way to host up to 20 addon domains in a single web hosting package. Hosting an additional domain in an existing web hosting package is significantly cheaper than hosting each domain in a separate web hosting package.
You can find the price of additional domain hosting in the PRICE LIST of our web hosting services.

You can see information about the additional domain slots from the customer area, by choosing “Web hosting” from the menu and by clicking on the username of the corresponding webhosting package.

If you wish to reduce the addon domain slot count, first remove unnecessary addon domains from cPanel, under menu “Domains” by choosing “Manage” near the corresponding domain and clicking on the “Remove Domain” on the next page.
Then log in to the Customer Area from our website, choose “Web hosting” from the menu, click on the web hosting package’s username and then click on the link “Re-synchronise cPanel account with customerarea”. Wait for 10 minutes, delete your order from “Orders/Invoices” and then re-add the order by choosing “Web hosting” or “Domains” from the menu and by clicking on the “EXTEND” button.

NB! If only e-mail addresses are needed for a domain and a simple redirect is sufficient (no separate website is needed), then an addon domain slot is not necessary for this domain. In this case you can add this domain as an alias. To add the domain as an alias, under “Domains” menu click on the “Create A new Domain” button. On the next page you need to tick the option “Share document root…”. After the domain has been added you will be able to create the redirect from the “Redirects” menu.
