Most users think they offer the same services.
However, the two are very different. IPPs host a company's or individual's Web site on their servers and post the site to the Internet. IPPs distinguish themselves by their ability to provide dedicated bandwidth to keep Web sites accessible. Because the IPP's bandwidth is devoted to hosting Web sites, connection to the Net is generally faster and more consistent, with fewer peaks and valleys. It is quite possible that from time to time your ISP will experience down time.
