Domain Names and DNS

Robert Andrews
November 23, 1998
11th and 12th Grade
Introduction to the Internet

Materials Needed:
Whiteboard and markers, worksheet copies.

11th and 12th grade students will apply their understanding of domain names to create a domain name for themselves as well as understand and use the DNS system.

In today's technologically advanced world, the Internet, especially web pages, are key to business. By knowing the make up of a domain and DNS, they can make their own page.

Anticipatory Set:
Students will be told about what they will be learning today and how that will help them create their own web page. The students will also be questioned on their previous knowledge of domain names. Students will turn off their monitors to focus their attention to the task at hand.

First the different top level domains will be reviewed. Then the students will be told about InterNic and the DNS process. The process from web browser request to return will be traced: browser to InterNic to DNS to server to browser.

The teacher will model on the whiteboard examples of different domain names. Students will then be showed how to check if a domain name is in use from the Messmer information page. From there, DNS will be explained and explored.

Check for Understanding:
Students will be called on to answer questions during class. These questions include:

  • What are possible top level domains?
  • What are some possible personal domain names?
  • How can you check if a domain is used?
  • How do you register a domain name?
Students also are invited to ask questions as the input and modeling is presented.

Guided Practice:
Students will fill out a worksheet with the teacher in class. This will be turned in and checked by the teacher. The teacher walking around the class will check this in progress. The teacher will also share their ideas on the worksheets with the class.

Independent Practice:
No independent practice is needed at this point since there is no practical assignment.

Students will fill out an electronic exit slip to be submitted over email from my web page at (link removed). The exit slip includes the following questions: what have they learned, what point they are currently at, and what items they are confused about. This will be used to start the next class.
