When you type a URL into your browser, or click a link on a Web page, your request is sent to a Domain Name System server or DNS server where the IP address and server location of the resource is acquired. The DNS keeps track of where everything is on the Internet including Web pages, email, and all other Internet resources. Typically, users use a DNS server provided by their Internet service provider. This week, however, Google is encouraging users to switch to its own new service named Google Public DNS.
Google claims that its new DNS service provides faster and more secure processing than your Internet service providers’. To switch to Google Public DNS, users are required to change the DNS settings in their router to point to Google’s DNS server addresses: 220.127.116.11 as the primary address and 18.104.22.168 for the secondary.
Some in the industry are concerned that Google will gain too much power if it is allowed to grow as a DNS service provider. DNS service providers have access to every Internet request that users make. If not regulated, that power could result in invasion of privacy and other civil rights abuses. At the very least it would give Google valuable insight into public interests and allow it to monetize that insight through its advertising services.
So far, most reviews of the service are unable to find any benefit to switching to Google Public DNS, except for individuals using substandard Internet service providers. However, over time, Google could develop services, especially in the area of information security that could make its DNS service more attractive.
