We do provide 'masked redirection' (i.e. frame redirections) as part of standard DNS services; if you want something beyond a standard 301 or 302 HTTP redirection (i.e. you want it to appear that the domains you are redirecting have their own website rather than showing a different domains' website) you can select this within the 'Setup/Edit Web Redirection' option using our free HTTP redirection.
Before using 'masked redirection', please ensure that your provider does support this feature with their services. If they do not support this, your website might not display or work as intended.
