Usually a single machine placed in a private residence can be used to host one or more web sites from a usually consumer-grade broadband connection. These can be purpose-built machines or more commonly old PCs. Some ISPs actively attempt to block home servers by disallowing incoming requests to TCP port 80 of the user's connection and by refusing to provide static IP addresses. A common way to attain a reliable DNS host name is by creating an account with a dynamic DNS service. A dynamic DNS service will automatically change the IP address that a URL points to when the IP address changes.[10]

Shared web hosting is a good option for businesses looking to keep costs down. A shared web hosting provider will host multiple sites, owned by multiple customers, on one server. The site owners share the costs of operating the server, so pricing is much lower than VPS or dedicated hosting, usually less than $10 per month. However, site owners are also sharing the server’s ability to transfer data, which means your site’s performance can be slow if one or more of your hosting neighbors experience a traffic spike.
While it doesn’t cost a penny, we’re adamant on keeping our free hosting sharp and up-to-date. Our Free shared web hosting is based on Apache, PHP, and MySQL. If you’ve been searching for a free hosting platform that supports both legacy and the newest PHP applications, stop looking. We support multiple PHP 5 versions, as well as the newest of PHP 7 to ensure maximum compatibility with anything you need!
Many web hosting services offer a low "starting price," but require you to prepay for two or three years of service to get that price. After the promotional period, the renewal price for some web hosting services can be two, three, or even four times the initial promotional pricing. While the initial deal might be incredible, the cost of transferring your site (or paying the added fee) in a couple of years may be something to consider.

Shared servers are the entry-level hosting option. They’re the cheapest and require minimal, if any, technical know-how. Multiple websites are hosted on a single server, and therefore share its resources such as data transfer and disk space. This can be the perfect option for a small- to a medium-sized site with fewer than 30,000 visitors per month.
SiteGround has the best support and good performance but all that comes with a price (high renewal cost). The cheapest plan starts at $3.95/mo (with the 12-month commitment) and renews at $11.95/mo. You can host 1 website and the plan includes 10GB SSD storage, unmetered bandwidth, and free SSL. Your purchase is backed by the 30-day money-back guarantee.

It shouldn't come as any surprise that, like other web host providers, A2 Hosting's unlimited plans aren't actually unlimited. It expect you to use its service like "similarly situated customers." This is like being on a highway. If everyone is going a few miles above the speed limit, you're probably okay, but if you're barreling down the fast lane past everyone else, you're probably going to be asked to slow down.
Whatever the case, this won’t reflect well on your website or business. If you’re a professional or hobbyist, consider this scenario: your business/blog is mentioned on the radio, TV, or in an article on a highly trafficked site. Suddenly you have 60,000 web visitors . . . and it’s gone. Your site crashes under the stampede. Poof! There goes all that free publicity.
