What does this feature mean? I’m looking at the hosting plan and it says it offers unlimited domains. Does this mean that I can run two separate sites (firstsite.com and secondsite.com) under the same hosting plan? They would just split the bandwidth and server space?
It means that you can host as many domains as you like, all sharing the same bandwidth and server space. You can throttle bandwidth on a per-domain basis. You will still need to cover the cost of all but one of your domain names.
