Internet hosting services include the required Internet connection; they may charge a flat rate per month or charge per bandwidth used — a common payment plan is to sell a predetermined amount of bandwidth and charge for any 'overage' (Usage above the predetermined limit) the customer may incur on a per GB basis. The overage charge would be agreed upon at the start of the contract.

Patent dispute

Web hosting technology has been causing some controversy, as Web.com claims that it holds patent rights to some common hosting technologies, including the use of a web-based control panel to manage the hosting service, with its 19 patents. In addition, Web.com sued GoDaddy as well for similar patent infringement.
