Hi Mark, This is only a problem if you want "naked domain" URLs to point to their website i.e. both http://customername.com and http://www.customername.com If not, then the CNAME www.customername.com -> portal.yourhosting.com is the only DNS record needed. If you do want naked domain URLs to work , my solutions in order of preference would be: 1. A URL Redirect on your customer's domain host's web server 2. A .htaccess file with Rewrite on their webserver (doesn't work on WIndows servers) 3. A third party redirection service such as wwwizer.com 4. A naked A record pointing to your IP address But if using 3 or 4, be aware of the potential problems with directing the entire domain elsewhere when the only thing you really want to redirect is http traffic. . I have not used wwwizer.com myself but have not seen any bad reviews of it and have seen it recommended in several places. Option A is simple to set up if your customer has CPanel etc access to their domain management. And here's how to do it for Godaddy hosted domains: http://support.unbounce.com/entries/261051#301 -- Stuart On 21 Sep 2012 at 14:21, Mark Breen wrote: > Hello All, > > I have a question related to CNAMEs, A Records and DNS. > > I have a site that hosts 20 sites. > Customers site is www.example.com > Customer currently points his A record to my IP address > Customer points his CNAME to his domain > (This is the usual configuration for most domains) > > My site is www.hostingsite.com > > My problem is if I change IP address, I have to ask 20 customers to update > their DNS details.
