Do Proxies Block ISP Providers?

by Melly Parker

When you open a site via a proxy server, the proxy is really opening the site -- you're just opening the proxy connection. While using a proxy server blocks your ISP information from the site to which you're connecting, it may not keep your information from your ISP itself. If your ISP can tell which site you're visiting from the URL on the proxy link that displays your page, it will have a record of the site you viewed.

Proxy Servers

Proxy servers mask your IP address by filtering your connection through other servers. They're designed to hide where the connection is coming from so that a person looking at his website's hits won't know that you were there. The services can help you protect your identity and personal information from malicious uses. It allows you to browse truly anonymously with regards to the owners of the sites you visit.

ISP Monitoring

Your ISP is able to monitor your Internet use very easily. In order to access a site, you have to go through the connection provided by your ISP, so it can see which connections you're making. For example, some people use proxies when trying to hide illegal downloading, not realizing that the ISP monitors usage and knows how much information people are uploading and downloading at any given time. When you use a proxy, your ISP knows you're using a proxy -- they see you connect to it. However, depending on which proxy you use, they may not know where the connection ultimately ends up.


One of the main uses of proxy servers is connecting to a blocked Web page. If you're at work, for example, and want to access a games site that's blocked, you can use a proxy server to work around the block, even though in many cases that's against company policy. Proxy servers also help keep your personal information private; proxies are sometimes part of firewalls for this reason. Though a record may be left of a visit to a site, the site owner won't know where the connection really came from.


In general, you should not use a proxy site to attempt to fool your ISP. Look at the URL displayed by the proxy server when you access a page via proxy, and if it includes information about the page you're visiting, the ISP will have that information as well. If your ISP's terms of service say that proxy use isn't allowed, using a proxy may invalidate your agreement, and your Internet access may be shut off.
