Domain names are pieces of Internet real estate that can be hosted from anywhere. They are markers for a Web project that has a specific location, but the domain name does not itself specify that location. The IP address provides much more information on where the hardware is that is operating the Web project and who has ownership or control of the particular Web space. That is why tools like DNS resolvers are important in Internet research and in making the Internet more transparent for users. For example, a user may look up or \u201cresolve\u201d a DNS that has a particular brand name to see whether that site is held by the company that trademarked the brand or not. This kind of transparency can also help users avoid certain types of Internet fraud or scams, and help make e-commerce more accessible to a wider audience.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>What Does DNS Resolver Mean?
