Please do not hardcode in DNS zone files any IP addresses that are outside your direct control. Doing so introduces breakage on customer sites as networks and resources are renumbered outside your control.
If you are browsing a "naked" domain name (one without the "www" prefix) and seeing this message, please ask the company hosting your DNS services to provide an HTTP redirect for the "naked" domain name, on an IP address within their control, so as to reach the fully-qualified "www" domain name web site.
Alternatively, move the hosting of your DNS zone file to the organization currently hosting the fully-qualified "www" web site.
Thank you.
