An Internet service provider (abbr. ISP, also called Internet access provider or IAP) is a business or organization that provides consumers or businesses access to the
Internet and related services. In the past, most ISPs were run by the phone companies. Now, ISPs can be started by just about any individual or group with sufficient money and expertise. In addition to Internet access via various technologies such as
dial-up and
DSL, they may provide a combination of services including Internet
transit,
domain name registration and hosting,
web hosting, and
colocation.
