Things we’ll explore today: 1) Explain how to access and connect to the Internet2) Analyze an IP address & domain name

Accessing the InternetThings You Will Need:• An ISP (Internet Service Provider)Some ISPs provide unlimited data usage for a fixed

monthly price.• A Modem with an Antenna• A Web BrowserA Web Browser is a program that allows you to surf

the web (For example, Firefox or Google Chrome)• An Email Programme

An Email service is essential to send and receive electronic mail, and is sometimes needed for configuration when connecting to a new ISP.

Connecting to the internet

• First, use the set up CD provided by the modem company. It will take you through the steps to setting it up.

• To connect to the internet, first go to your internet connection on your task bar.

• Next, simply look through the networks available and choose yours. Once done you should be able to access your internet.

Recognise any of these logos?

Chances are, you’ve chanced across each symbol quite a few times; such is the power of the internet…

What is an IP address?

• It is a unique identifier for each machine on a network. It is used to send data to specific computers on a network.

• There are two standards for IP addresses: IPv4 and IPv6

• In the next two slides, we will analyse both of them.

IPv4 (Internet Protocol version 4)• IPv4 uses 32 binary bits to create a

single unique address on a network. • With this system, there are

4,294,967,296 unique combinations, which as of now have almost run out.

• It is the fourth version in the development of Internet Protocol and it is the first version to have been widely deployed.

IPv4 Address

IPv6 (Internet Protocol version 6)• IPv6 on the other hand uses 128 binary bits to create a single unique address on a network. • It was developed to deal with the long-anticipated problem of IPv4 address exhaustion. •In the IPv6 system, there are 2128, or about 3.4×1038 possible addresses, or more than 7.9×1028 times more than IPv4. •As IPv4 and IPv6 were not designed to be interoperable, the transition to IPv6 will most likely be complicated.

IPv6 Address

What is an Domain Name?

• Short for Domain Name System, DNS is an Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they’re easier to remember.

• Every time you use a domain name (e.g. google.com), you use the internet’s domain name servers to translate the domain name into machine-readable IP addresses (e.g. 64.233.167.99)
