Internet Addresses

1. What is a URL?

Uniform (or universal) resource locator, the address of a World Wide Web page.

2. What is an IP address and how is it related to a URL?

The browser communicated with a name server to translate the server name "www.google.com.au" into an IP Address which it uses to connect to the server machine. The browser then formed a connection to the server at that IP address on port 80.

3. Given our school website's URL is http://www.mcauley.nsw.edu.au, what is our domain name and what protocol do you need to use to access the site?

Domain Name: mcauley.nsw.edu.au

Protocol: 'http' (hypertext transfer protocol)

4. In the context of an IP address, what is an octet?

IP stands for Internet protocol, and these addresses are 32-bit numbers, normally expressed as four "octets" in a "dotted decimal number." The four numbers in an IP address are called octets because they can have values between 0 and 255.
