Checking or determining who is your Internet service provider, or ISP, can be easily accomplished by finding the corresponding bill payment or by accessing specific websites that instantly display your system information. Your ISP is the company that provides you with the necessary equipment to access the Internet, such as a cable modem or DSL line. In many cases, the Internet provider also allows you to create your own email account displaying the company name as part of the host name. This company may also handle your phone or cable television service.
Launch an Web browser, such as Internet Explorer, Firefox or Safari.
Navigate to Spyber.com, MyIP.com or IP-Address.com. (See Resources for links.)
Check the name of your Internet service provider by viewing the information that corresponds to the "ISP" field. Additional information displays, such as your IP address, host, country, state and city.
