Evaluate the reliability of each URL Understanding domain names and URLs can help in estimating how reliable the information is on a site. EDU was originally designed for 4-year, degree granting colleges and universities, but has been expanded to a variety of educational institutions. Just because information is on a college or university site should not lead you to give it added credibility. A famous case from the Midwest is a professor's Web page on a Big Ten university's Web site, which claimed the Holocaust never happened. GOV indicates agencies and branches of the U.S. government, expanded now to some state governments.
NET designates entities and networks that are part of the Internet's infrastructure.
These domains, particularly if an Internet Service Provider, often have Web pages for their subscribers. The ORG domain is used for miscellaneous entities that don't fit under any other top level domain. Keep that in mind when evaluating what you've found on that site. Name is their user name on that network. The point here is not that information on these pages is not correct or relevant to your search.
