Every virtual server plan includes a static IP address.
While some hosting companies use name-based hosting, Hosting '4' All provides an IP address for all accounts so that all Internet traffic can find your website.
Without a static IP, the HTTP 1.0 protocol is not supported for the IP-less virtual domain.
The HTTP 1.0 protocol, still used by some web browsers, completely unsupports IP-less virtual domains. This include all Netscape 2.x and MSIE 3.x browsers, along with some AOL browswers.
